1. Introduction to RtBrick BGP
The RtBrick Full Stack (RBFS) is a distributed, web-scale network operating system based on micro-service architecture and packaged in a Linux container currently based on Ubuntu 18.04. The RBFS decreases the complexity of a network by providing users with capabilities such as composability, programmability, and elasticity in a visionary way.
The RBFS operating system operates on the leaf and spine framework. This framework provides the network operators with methods to configure and manage a network brick by brick, and provides full control of the network so the focus can be on the deployment of the new services and not the constant juggling of hardware.
1.1. BGP Overview
BGP is a standard exterior gateway protocol (EGP) supported by RtBrick. BGP is considered a “Path Vector” routing protocol and maintains a separate routing table based on shortest Autonomous system (AS) path and various other route attributes.

2. RBFS BGP Instance Hierarchy
The RBFS uses a distinct hierarchy for the BGP statements and commands. When installed, the RBFS runs a default instance named “default.” In most applications, more instances are needed, and many configuration statements apply to various levels of the statement hierarchy.
You can apply BGP configuration statements and commands at the instance, address family, or protocol BGP hierarchy level.
This BGP hierarchy can be represented as:
Global BGP Configuration - Router ID - Local AS - Cluster ID - Domain Name - Host Name - Local Preference - Out Metric - Protocol Preference - Timer: Hold Time - Timer: Keep Alive - Timer: Connect Retry Instance BGP Address Family Configuration - Default-Information Originate - Download-Count - Multipath - Remote AS - Local AS - EBGP-Multihop - Any-AS Instance BGP Peer-group Address family Configuration - Extended Nexthop - Update Nexthop - Nexthop Unchanged - Nexthop Self - Default Information Originate - Remove Private AS - Route Reflector Client Instance BGP Peer Configuration
2.1. Address Family
The address family configured at the instance level determines the types of address families that the virtual routing and forwarding (VRF) instance supports. At this level, you also configure the route target (RT), and the import and export policies for the instance. The forwarding daemon (FWDD) uses these configuration statements to create the VRF tables for each address family. Note that the route distinguisher (RD) is configured under the instance hierarchy level.
At the BGP protocol level, the address family configuration is used to determine which address families BGP supports. Multiple commands exist under this hierarchy level.
At the BGP peer group level, the address family configuration is used to determine which address families are needed to negotiate usage with the other BGP peers in the group.
There is no configuration under the peer hierarchy level. This statement establishes the peer, and all peers must be associated with a peer group. All of the parameters that apply to a peer are determined at the peer-group hierarchy level.
For example, this sequence configures IPv4 unicast support for the vrf1 instance:
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv4 unicast
2.2. Redistribute
BGP determines support for route redistribution based on address family. The selected address family can redistribute local interface routes, static routes, routes learned by IS-IS, and so on. Complete redistribute statement information and examples are included in other sections.
3. BGP Global Configuration Commands
When it comes to BGP configuration, global BGP commands configure the routing instance, and instance BGP commands configure how BGP behaves in the instance.
This describes the BGP global commands. These commands establish the instance, the route distinguisher (RD), and the route target (RT) for BGP to use.
3.1. Instance
Configure and log into the RBFS instance
Command arguments
<instance-name> |
Name of the routing instance |
Example
root@rtbrick: cfg> set instance ip2vrf root@rtbrick: cfg> commit
3.2. Route Distinguisher
Configure the route distinguisher (RD) to define unique routes within an IPv4 network. Provider Edge (PE) routers use route distinguishers to identify which virtual private network (VPN) a packet belongs to in a PE network.
Command arguments
<instance-name> |
Name of the routing instance |
<ipv4-address> |
The IPv4 address to use for the RD (in dotted decimal format) |
<rd-value> |
Specifies the route distinguisher value |
Example
root@rtbrick: cfg> set instance ip2vrf rd 192.1.4.1:65001 root@rtbrick: cfg> commit
The following example shows the route-distinguisher configured on an instance.
supervisor@ixr_pe1: op> show config instance ip2vrf route-distinguisher 192.0.1.2:1 { "rtbrick-config:route-distinguisher": "192.0.1.2:1" } supervisor@ixr_pe1: op>
3.3. Route Target
Configure the route target (RT) to use to transfer routes between VRFs and VPNs. The RT identifies a subset of routes within the BGP VPNv3 unicast table that should be used in a VRF for a particular customer. You configure an RT for importing or exporting routes, or both.
Command arguments
import |
Use this RT for imported routes |
export |
Use this RT for exported routes |
target:<rt-value> |
The value to use for the RT, in the same format as the RD |
Example: Configure an RT for import and export routes
root@rtbrick: cfg> set instance ip2vrf address-family ipv4 unicast rt import target:192.1.4.0:11 root@rtbrick: cfg> set instance ip2vrf address-family ipv6 unicast rt import target:192.1.4.0:21 root@rtbrick: cfg> commit
The following example shows an interface where import and export routes are configured.
supervisor@ixr_pe1: op> show config instance ip2vrf address-family ipv4 unicast route-target { "rtbrick-config:route-target": { "import": "target:192.1.4.0:11", "export": "target:192.1.4.0:21" } } supervisor@ixr_pe1: op>
4. BGP Instance Configuration Commands
This section describes the commands used to configure BGP in an instance.
4.1. bgp
You must enable BGP inside an instance before you configure the BGP-specific instance options. When this enable command is successfully executed, the mode is changed from edit to set.
edit protocol bgp
Example: Configure BGP for the vrf1 instance
[ edit instance vrf1 ] root@spine1:confd> edit protocol bgp
4.2. address-family (and BGP Options)
You must configure the BGP address families if you are using route redistribution, load balancing, or other advanced features. By default, BGP neighbor sessions support IP4v unicast and multicast address families.
<instance-name> |
Name of the instance |
<address-family-afi> |
Enables the address family identifier (AFI) IPv4 or IPv6 |
<address-family-safi> |
Enables the subsequent address family identifier (SAFI) options: unicast, labeled-unicast, or vpn-unicast |
Example: Enable the IPv4 unicast address family for BGP on the vrf1 instance
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv4 unicast root@rtbrick: cfg> commit
In addition to the basic family support, you can also configure a number of options.
Supported options, detailed in sections below, are:
default-information |
Configure default route information to distribute |
download-count |
Forward packets over multiple paths, but set maximum prefixes to use |
download-policy |
Establish a policy for downloading routes |
multipath |
Enable load sharing among multiple BGP paths |
redistribute |
Enter redistribution configuration mode |
retain-route-target |
Retain VPN routes for all route targets |
srgb |
Establish Segment Routing Global Block for segment routing |
You should always configure BGP to distribute a default route. |
Example: Configure BGP to distributes a default IPv4 unicast address in the vrf1 instance
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv4 unicast default-information originate true root@rtbrick: cfg> commit
4.3. download-count
This statement is for temporary use until full routing policy support is configured. Use this statement to configure the number of prefixes that the BGP unicast session can download to the forwarding daemon (FWDD). BGP downloads the attribute information (community, extended community, and as-path) for prefixes to the Routing Information Base (RIB) and Forwarding Information Base (FIB) for advertising.
You can assign counters based on BGP prefixes and attributes on a per-input interface basis.
set protocol bgp address-family <address-family-afi> <address-family-safi> unicast download-count <count-number>
<address-family-afi> |
Enables the IPv4 or IPv6 address families |
<address-family-safi> |
Enables the subsequent address family identifier (SAFI) options: unicast, labeled-unicast, or vpn-unicast |
unicast |
BGP distributes unicast routes |
download-count |
Count prefixes |
<count-number> |
Number of prefixes to forward over multiple paths |
Example: Configure BGP for a maximum of 40 prefixes
[ edit instance vrf1 ] root@spine1:confd> set protocol bgp address-family ipv4 unicast download-count 40
4.4. download-policy
Apply the BGP routing policy for downloaded routes. The policy is defined elsewhere.
set protocol bgp address-family <address-family-afi> <address-family-safi> download-policy <policy-name>
<address-family-afi> |
Enables the IPv4 or IPv6 address families |
<address-family-safi> |
Enables the subsequent address family identifier (SAFI) options: unicast, labeled-unicast, or vpn-unicast |
<policy-name> |
Name of the policy to apply |
The policy is NOT configured here. Routing policy configuration is covered in another chapter. |
Example: Configure download policy
[edit] root@spine1:confd> set bgp address-family ipv4 unicast download-policy fibpolicy
4.5. multipath
Allow load sharing among the configured number of multiple Exterior BGP (EBGP) and Internal BGP (IBGP) paths.
<address-family-afi> |
Enables the IPv4 or IPv6 address families |
<address-family-safi> |
Enables the subsequent address family identifier (SAFI) options: unicast, labeled-unicast, or vpn-unicast |
<number-of-paths> |
Number of paths that can be installed in the forwarding table. This is an integer in the range 0 to 255. |
Example: Configure multipath for a value of 10 forwarding table entries
root@rtbrick: cfg> set instance protocol bgp address-family ipv4 unicast multipath 10 root@rtbrick: cfg> commit
4.6. redistribute

IS-IS and OSPF have additional options detailed below. |
Example: Configure redistribution on direct routes into BGP.
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv4 unicast redistribute direct root@rtbrick: cfg> commit
4.6.1. IS-IS Redistribute Options
If you configure the redistribution of IS-IS routes, you have the option of testing for a match on either level-1 or level-2 IS-IS routers. The syntax is as follows:
set instance <instance> protocol bgp address-family <address-family-afi> <address-family-safi> redistribute isis policy-map <policy-map>
<address-family-afi> |
Enables the IPv4 or IPv6 address families |

4.7. retain-route-target
By default, the forwarding table retains the VPN routes for all route targets when the roputing protocol process shuts down. If you disable this retention of route targets, the VPN routes are removed from the forwarding table when the routing protocol shuts down.
set instance <instance> protocol bgp address-family <address-family-afi> <address-family-safi> retain-route-target disable
<address-family-afi> |
Enables the IPv4 or IPv6 address families |
<address-family-safi> |
Enables the subsequent address family identifier (SAFI) for vpn-unicast (the only family supported) |
[edit] root@rtbrick: cfg> set instance ip2vrf bgp address-family ipv4 vpn-unicast retain-route-target disable
4.8. srgb
The Segment Routing Global Block (SRGB) is the range of label values reserved for segment routing (SR). These values are assigned as segment identifiers (SIDs) to SR-enabled network nodes and have global significance throughout the routing domain.
SRGB is supported only for labeled unicast. |
You must specify the base starting value for the labels (a number greater than 15), a range for the labels, and an index within the label range.

root@rtbrick: cfg> set instance default protocol bgp domain-name leaf-1 root@rtbrick: cfg> commit
4.11. enforce-first-as
By default, the BGP routing process enforces the First AS feature. This feature discards updates received from an eBGP peer if the peer does not list its own AS number as the first segment in the AS_PATH BGP attribute.
To disable the First AS feature and accept updates without the peer’s source AS matching the first AS in the AS_PATH attribute, configure the feature to disable the enforce First AS feature.
set instance <instance> protocol bgp enforce-first-as disable
<instance> |
Name of the BGP instance |

4.20. peer-group
Configure a name for a peer group of BGP routers. Neighbor peers with the same update policies can be grouped as peers (equals) to simplify the initial configuration and updates. Peers share the same policies such as route maps, distribution lists, filter lists, update source, and so on, so peer groups only need one configuration statement for these values.
set instance <instance> protocol bgp peer-group <peer-group-name> ( address-family <address-family-afi> | any-as <true|false> | ebgp-multihop <hop-count> | link-local-nexthop-only <true|false> | local-as <as-number> | remote-as <as-number>)

root@rtbrick: cfg> set instance ip2vrf protocol bgp peer-group spine any-as root@rtbrick: cfg> set instance ip2vrf protocol bgp peer-group spine ebgp-multihop 3 root@rtbrick: cfg> set instance ip2vrf protocol bgp peer-group spine add-path 20 send-only root@rtbrick: cfg> commit
The full set of address family names is listed under the address-family configuration statement. |
4.21. address-family (peer-group)
You must configure the BGP address families for a peer-group if you are using route redistribution, load balancing, or other advanced features. Note: The advanced features are NOT configured here, but under the BGP instance. By default, BGP neighbor sessions support IP4v unicast and multicast address families.
set instance <instance> protocol bgp peer-group <peer-group-name> address-family <address-family-afi> <address-family-safi> [ options ]
<instance> |
Name of the BGP instance |
<peer-group-name> |
Name of the peer group supporting these families |
<address-family-afi> |

policy |
Apply a routing policy to the peer group |
remove-private-as |
Remove private AS numbers from routes advertised to group peers |
route-reflect-client |
Configure this peer as a route reflector client |
update-nexthop |
Update the nexthop for routes advertised to this peer group |
Example: Enable the IPv4 unicast address family for BGP on the vrf1 instance and make the peer a route-reflector client
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv4 unicast route-reflect-client root@rtbrick: cfg> commit
4.22. peer
Configure parameters for a, IPv4 or IPv6 BGP peer. A BGP peer is a BGP router that has an active TCP connection to another BGP router. To establish point-to-point connections between peer autonomous systems (ASs) for eBGP or within the AS for iBGP, you configure a BGP session on an interface. When you configure a BGP peer, the configuration adds the IP address of the peer in the specified autonomous system to the multiprotocol BGP (mBPG) neighbor table maintained in the local router.
set instance <instance> protocol bgp peer ( ipv4 | ipv6) <peer-address> <update-source> peer-group <peer-group-name>
instance |
Name of the BGP instance |
(ipv4 | ipv6 ) |
Configure either an IPv4 or IPv6 BGP peer |
peer-address <ip-address> |
Configure the peer IPv4 or IPv6 address. You cannot use this option with the interface option below. |
update-source <ip-address> |
Configure an IP address to use as the source for packets sent to the peer address |
peer-group <peer-group-name> |
Assign this peer to this peer group |
The peer-address and interface options are mutually exclusive. In other words, you cannot locate a peer by both interface and address; only one or the other. |
There are three main peer types to configure:
-
IPv4 peers
-
IPv6 peers
-
IPv6 link local peers (dynamic peers)
Each type has a general peer configuration format associated with it:
-
(IPv4 peer) set instance protocol bgp peer ipv4 peer-address <ipv4-address> update-source <ipv4-address> peer-group <group-name>
-
(IPv6 peer) set instance protocol bgp peer ipv6 peer-address <ipv6-address> update-source <ipv6-address> peer-group <group-name>
-
(IPv6 link-local dynamic peer) set instance protocol bgp peer interface <interface-name> peer-group <group-name> Note that IP6v link-local peers configure the interface. The following examples configure a peer of each type.
Example 1: Configure an IPv4 BGP peer and assign the peer to the spine peer group.
root@rtbrick: cfg> set instance ip2vrf protocol bgp peer ipv4 192.168.1.1 192.168.1.2 peer-group spine root@rtbrick: cfg> commit
Example 2: Configure an IPv6 peer and assign the peer to the spine peer group.
root@rtbrick: cfg> set instance ip2vrf protocol bgp peer ipv6 1::1 1::2 peer-group spine root@rtbrick: cfg> commit
Example 3: Configure an IPv6 dynamic peer on interface ifl-0/0/1/1/1 and assign the peer to peer group spine.
root@rtbrick: cfg> set instance protocol bgp peer interface ifl-0/0/1/1/1 peer-group spine root@rtbrick: cfg> commit

7. Routing Policies and Examples
This section covers the RtBrick way of configuring routing polices.
7.1. The Role of Routing Policy
Routing Policies are the rules that allows you to control and modify the default behaviour of the routing protocols such as BGP and IS-IS. To use routing policies, you configure policies, and then apply policies to peer groups or instances.
RtBrick supports attaching a BGP routing policy at two levels:
-
Peer group address-family level
-
Instance address-family level
In each case, you can apply the policy as an import or export policy and filter. As expected, import filters determine which routing updates are accepted and export filters determine which routes are advertised to other peers.
7.2. Peer Group and Instance Details
An import policy, when applied to an address family at the peer group level, examines all incoming routes from all BGP peers in the peer group, but only for that address family.
An export policy, when applied to an address family at the peer group level, examines all outgoing routes to all BGP peers in the peer group. but only for that address family.
At the instance level, routing policies that are applied to an address family can work as import or export policies, but for the instance as a whole.
An import policy, when applied to an address family at the instance level, examines all incoming routes before accepting the information only from global or default tables to other instance or VRF table.
An export policy, when applied to an address family at the instance level, examines all outgoing routes before sending the information from the VRF to global, and then to the vpn table (default).
7.3. Attachment Point
Policies are useful when they are applied to routes, and for policies to be applied to routes they need to be made known to routing protocols. In BGP, for example, there are several situations where policies can be used, the most common of these is defining import and export policy. The policy attachment point is the point in which an association is formed between a specific protocol entity, in this case a BGP neighbor, and a specific named policy.
Attachment Point for Export Policy to peer-group
Export policies attached to a BGP peer-group, can be used to apply certain conditions based on any of the route attributes and advertise to the peers, only those route that match our criteria.
set instance ip2vrf protocol bgp peer-group leaf1 address-family ipv4 vpn-unicast policy policy-name p2 export
Input
rtb bgp.appd.1 show datastore table dump default.bgp.routing-table.ipv4.vpn-unicast
Output
rtb bgp.appd.1 show datastore table dump default.bgp.1.peer-group.leaf1.ipv4.vpn-unicast
Attachment Point for Import Policy to peer-group
Import policies attached to a BGP peer-group, can be used to filter and modify based on any of the route attribute that we wish to.
set instance ip2vrf protocol bgp peer-group rr address-family ipv4 unicast policy <POLICY-NAME> import
Input
rtb bgp.appd.1 show datastore table dump default.bgp.rib-in.ipv4.unicast.<peer_ip>.<local_ip>
Attachment Point for Export Policy to main Instance
Export policies attached to an instance, help us to modify the attributes of a route present in the instance before exporting them as VPN routes. If we would to attach an extended_community, nexthop, community etc before exporting them as VPN routes, we can do so by using this attachment point.
set instance ip2vrf address-family ipv4 unicast policy policy-name p1 export
Input
rtb bgp.appd.1 show datastore table dump ip2vrf.bgp.1.fib-local.ipv4.unicast rtb bgp.appd.1 show datastore table dump ip2vrf.bgp.rib-in.ipv4.unicast.0.0.0.0
Output
rtb bgp.appd.1 show datastore table dump default.bgp.rib-local.ipv4.vpn-unicast
Attachment Point for import policy to main instance
Import policies attached to an instance, help us to modify the attributes of a route/route-list before importing into the instance. The matching criteria can be any of the route attributes such as prefix, as_path, community, extended_community etc.
set instance ip2vrf address-family ipv4 unicast policy policy-name p1 import
Input
rtb bgp.appd.1 show datastore table dump default.bgp.fib-local.ipv4.vpn-unicast
Output
rtb bgp.appd.1 show datastore table dump ip2vrf.bgp.1.rib-local.ipv4.unicast

8. BGP MD5-Authentication Configuration Commands
Border Gateway Protocol (BGP) supports the authentication mechanism using the Message Digest 5 (MD5) algorithm. When authentication is enabled, any Transmission Control Protocol (TCP) segment belonging to BGP exchanged between the peers is verified and accepted only if authentication is successful. For authentication to be successful, both the peers must be configured with the same password. If authentication fails, the BGP neighbor relationship is not be established.

9. Configuring IPv6 Provider Edge over MPLS (6PE)
6PE solution enables IPv6 communication over MPLS IPv4 core network. IPv6 reachability information is associated with a label and transferred through MP-BGP(AFI: 2 SAFI:4). IPv4 mapped IPv6 address is used to encode the nexthop information. The edge nodes in MPLS IPv4 core have to support both IPv4 and IPv6. The IPv6 Labeled Unicast routes received from the 6PE peer is considered as IPv6 unicast routes and installed in IPv6 Unicast FIB. The received Label is attached to the IPv6 data traffic at the Ingress node and tunneled through a MPLS tunnel(SR) to the egress node, the label identifies the IPv6 traffic and the egress node would POP the label and forward the ipv6 traffic towards the destination.
9.1. Enabling 6PE for a BGP Address-family
9.1.1. Enable ipv6 unicast for BGP instance
The following command enables IPv6 unicast address-family under BGP instance.
Syntax
set instance <instance> protocol bgp address-family ipv6 unicast
Example
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv6 unicast root@rtbrick: cfg> commit
9.1.2. Enable ipv6 labeled-unicast for BGP instance
The following command enables IPv6 labeled-unicast address-family under BGP instance.
Syntax
set instance <instance> protocol bgp address-family ipv6 labeled-unicast
Example
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv6 labeled-unicast root@rtbrick: cfg> commit
9.1.3. Setting lookup SAFI for IPv6 unicast prefixes
The following command resolves the nexthop address associated with the 6PE route on IPv4 labeled-unicast as nexthop for 6PE route is IPv4 mapped IPv6 address..
Syntax
set instance <instance> protocol bgp address-family ipv6 unicast resolve nexthop safi labeled-unicast
Example
root@rtbrick: cfg> set instance ip2vrf protocol bgp address-family ipv6 unicast resolve nexthop safi labeled-unicast root@rtbrick: cfg> commit
9.1.4. Enable IPv6 labeled-unicast AFI/SAFI under peer-group
The following command enables IPv6 labeled-unicast address-family under peer-group to which iBGP peer is attached.
Syntax
set instance <instance> protocol bgp peer-group <peer-group-name> address-family ipv6 labeled-unicast
Example
root@rtbrick: cfg> set instance ip2vrf protocol bgp peer-group leaf1 address-family ipv6 labeled-unicast root@rtbrick: cfg> commit
9.1.5. Setting send-label for IPv6 unicast AFI/SAFI
The following command enables advertisement of the label along with the IPv6 unicast route through iBGP session.
Syntax
set instance <instance> protocol bgp peer-group <peer-group-name> address-family ipv6 unicast send-label
Example
root@rtbrick: cfg> root@spine1:confd> set instance ip2vrf protocol bgp peer-group leaf1 address-family ipv6 unicast send-label root@rtbrick: cfg> commit
