1. Introduction to RBFS IS-IS
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. The Intermediate System-to-Intermediate System (IS-IS) protocol is an interior gateway protocol (IGP) that uses link-state information to make routing decisions.
1.1. IS-IS Overview
IS-IS, or Intermediate System to Intermediate System, is an open standard routing protocol. ISO published the standard as a way to route datagrams as part of their OSI stack. IETF later republished the standard, and added IP route support.
It is a link-state routing protocol, similar to OSPF. It forms neighbor adjacencies, has areas, exchanges link-state packets, builds a link-state database and runs the Dijkstra SPF algorithm to find the best path to each destination, which is installed in the routing table.
This guide provides the various IS-IS configuration and show CLI commands for RBFS.
2. Configuring IS-IS
The basic IS-IS configuration tasks that must be performed are:
-
enable IS-IS protocol
-
configure IS-IS Instance
-
configure system ID
-
configure area addresses
-
configure instance level
-
-
configure interfaces
-
configure address-family
2.1. Entering configuration mode
The following example shows how to enter the configuration mode.
root@rtbrick:~$ cli root@rtbrick: op> switch-mode config Activating syntax mode : cfg [config] root@rtbrick: cfg>
From this prompt, you can enter the set commands to configure the various IS-IS components.
2.2. Enabling IS-IS Protocol
To enable IS-IS, you must configure the ISIS protocol under a specific instance.
instance |
Name of the IS-IS instance |
Example
root@rtbrick: cfg> set instance ip2vrf protocol isis root@rtbrick: cfg> commit
2.3. Configuring an IS-IS Instance
After enabling IS-IS, the following parameters can be configured in an instance.
2.3.1. Configure the System ID
A system ID uniquely identifies a device.
instance |
Name of the IS-IS instance |
system_id |
specifies the system ID of the device. |
Example
root@rtbrick: cfg> set instance ip2vrf protocol isis system-id 1920.0100.4001 root@rtbrick: cfg> commit
2.3.2. Configuring the ISO Area Addresses
instance |
Name of the IS-IS instance |

2.3.4. Configuring the Router ID
This command allows add a 'router-id' configuration option to IS-IS and advertise the configured router id in TLV 132 (IP Interface Address) and TLV 134 (TE Router ID)as part of the LSP.
Syntax
Command arguments

2.3.12. Ignoring the attached bit on IS-IS
This configuration allows you to enable the routing device to ignore the attached bit on incoming Level 1 link-state PDUs. If the attached bit is ignored, no default route, which points to the routing device which has set the attached bit, is installed.
Syntax
Command arguments
<instance-name> |
Name of the instance |

Example
admin@rtbrick: cfg> set instance <instance-name> protocol isis ignore-attached-bit true admin@rtbrick: cfg> commit
2.3.13. Configuring no-mpls-transit-route
This configuration allows you to prevent IS-IS from installing the transit path for the received Segment Index for IS-IS segment routing. This configuraton should be used only if the router is an edge node which is neither expected to act as "router on a stick" or as a transit node in any topology change.
Syntax
<instance-name> |
Name of the instance |
<true/false> |
Specifies whether no-mpls-transit-route configuration is enabled or not |
Example
supervisor@isis_ler1: cfg> set instance <instance-name> protocol isis no-mpls-transit-path true supervisor@isis_ler1: cfg> commit
2.3.14. Disabling IP version 6 (IPv6) routing
By default, RBFS supports both IPv4 and IPv6 routing. When IS-IS is used only for IPv4, you can disable the IPv6 routing so that RBFS does not send IPv6 data.
Syntax
<instance-name> |
Name of the instance |
<true/false> |
Specifies whether the ipv6-disable configuration is enabled or not. When you set this value to "true", it indicates that IPv6 configuration is disabled. |
Example
supervisor@isis_ler1: cfg> set instance default protocol isis ipv6-disable true supervisor@isis_ler1: cfg> commit
The example below shows the configuration after ipv6-disable is performed.
