1. IGMP Overview
Internet Group Management (IGMP) protocol allows a host to advertise its multicast group membership to neighbouring switches and routers. IGMP is a standard protocol used by the TCP/IP protocol suite to achieve dynamic multicasting.
There are two components in the IGMP solution:
-
IGMPv2/v3 Client: It sends Join or Leave messages to a multicast group. Typical example of a client is a SET-TOP box. The IGMP client can respond to any IGMP general queries or group-specific queries that are received.
-
Multicast Router: The recipient of IGMP Join/Leave message. After receiving the message, it determines whether the corresponding message needs to be processed or not. After processing the IGMP messages, it sends this information to its multicast upstream router. Along with this, it can program certain entries in its routers which results in forwarding specific multicast packets on that interface.
1.1. IGMPv3 Lite
IGMP version 3 adds support for "source filtering", that is, the ability for a system to report interest in receiving packets only from specific source addresses, or from all but specific source addresses, sent to a particular multicast address. That information may be used by multicast routing protocols to avoid delivering multicast packets from specific sources to networks where there are no interested receivers.
The RtBrick IGMP v3lite solution adds support for source filtering. Source filtering enables a multicast receiver host to signal from which groups it wants to receive multicast traffic, and from which sources this traffic is expected. That information may be used by multicast routing protocols to avoid delivering multicast packets from specific sources to networks where there are no interested receivers.
IGMP Version 3 will help conserve bandwidth by allowing a host to select the specific sources from which it wants to receive traffic.Also, multicast routing protocols will be able to make use of this information to conserve bandwidth when constructing the branches of their multicast delivery trees.

2.8.10. Configuring SSM Mapping
SSM mapping takes IGMPv2 reports and converts them to IGMPv3. In case of legacy devices, there could be a possibility that BNG might receive IGMPv2 membership reports. If BNG receives an IGMPv2 membership for a specific group G1, BNG uses the SSM mapping configuration to determine one or more Source (S) addresses for a given group. This SSM mappings are translated to the IGMPv3 joins like IGMPV3 JOIN INCLUDE (G, [S1, G1], [S2, G1] and so on) and BNG continues to process as if it has received from the subscriber.
To configure an SSM mapping policy, enter the following command:.
Syntax
Command Parameters

Example

2.9. Configuring SSM Mapping Policy
SSM mapping takes IGMPv2 reports and converts them to IGMPv3. In case of legacy devices, there could be a possibility that BNG might receive IGMPv2 membership reports. If BNG receives an IGMPv2 membership for a specific group G1, BNG uses the SSM mapping configuration to determine one or more Source (S) addresses for a given group. This SSM mappings are translated to the IGMPv3 joins like IGMPV3 JOIN INCLUDE (G, [S1, G1], [S2, G1] and so on) and BNG continues to process as if it has received from the subscriber.
The example below shows a sample configuration of the ssm-policy.
admin@rtbrck: cfg> set policy statement ssm ordinal 1 match rule 1 type mcast-route-ipv4-group admin@rtbrck: cfg> set policy statement ssm ordinal 1 match rule 1 value-type complete admin@rtbrck: cfg> set policy statement ssm ordinal 1 match rule 1 match-type or-longer admin@rtbrck: cfg> set policy statement ssm ordinal 1 match rule 1 value 233.1.1.0/24 admin@rtbrck: cfg> set policy statement ssm ordinal 1 action rule 1 type mcast-route-ipv4-source admin@rtbrck: cfg> set policy statement ssm ordinal 1 action rule 1 operation overwrite admin@rtbrck: cfg> set policy statement ssm ordinal 1 action rule 1 value 100.1.1.1/32

2.11. Configuring the IGMP Static Joins on an Instance
After an interface on a multicast device is configured to statically join an IGMP group, the multicast device considers that the interface has static multicast group members and sends multicast packets to this interface, regardless of whether hosts connected to this interface request the multicast packets.
To configure an IGMP static join on the default instance, enter the following command:
Syntax
Command Parameters
<instance> |
Specifies the instance name |
<group> |
Specifies the multicast address |
<source> |

5. Multicast VPN
5.1. Introduction
The Multicast VPN (MVPN) feature provides the ability to support multicast over a Layer 3 VPN. Multicast allows the efficient distribution of information between a single multicast source and multiple receivers. IP multicast is used to stream video, voice, and data to an MPLS VPN network core.
RBFS operates on the LEAF and SPINE devices. The Leaf layer delivers access services to subscribers or assets, and the spine provides connectivity to the network. The leaf is fully meshed into the Spine and this arrangement is usually referred to as an IP CLOS architecture. The 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 without any dependencies on hardware. The two tier CLOS architecture allows future extensibility through the leafs that can be added without disturbing the existing topology, so long as they are fully meshed with the spines. Leafs and spines are connected via 100G ports.
LEAF and SPINES are Edge Core devices with Broadcom BCM 88375 (Qumran) with KBP running RBFS stack. Each of these devices are configured with BGP to bring up the fabric. BGP neighbors are in the default instance and the following address families are enabled by default in the peer-group template:
-
IPv6 Unicast (to resolve the next hops)
-
IPv6 Labeled Unicast (to resolve the next hops)
-
VPNv4 (to transport subscriber IPv4 routes, LI End point, LAC endpoint, RADIUS endpoint)
-
VPNv6 (to transport subscriber IPv6 routes, RADIUS endpoint)
-
MVPN (to carry subscriber multicast routes)
5.2. Enabling Multicast Address Family in Fabric
To advertise the subscriber multicast routes, you need to enable MVPN address family in the fabric. RBFS MVPN implementation is based on RFC 6513, “Multicast in MPLS/BGP IP VPNs” and RFC 6514, “BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs”.
Before you can enable IPTV service to subscribers, Multicast/MVPN can be enabled in the fabric to achieve this.
-
Enable Multicast address family under global instance
-
Enable the Multicast address family under BGP for the instance
5.2.1. Enabling Multicast Address Family Under Global Instance
The address-family command places the switch in address family mode to configure the address family activity level of individual BGP neighbor addresses. The switch supports these address families:
-
ipv4
-
ipv6
-
mpls
To configure multicast IPV4 address family under the global instance, enter the following command:
5.2.2. Enabling Route-Target Address Family in the Fabric
Similar to the unicast address family, MVPN address family defined under VRF instance needs an import and export route target. The below example shows defining the MVPN address family and corresponding attributes under IP2VRF.
admin@leaf: cfg> set instance ip2vrf address-family ipv4 multicast route-target export target:192.1.4.0:14 admin@leaf: cfg> set instance ip2vrf address-family ipv4 multicast route-target export target:192.1.4.0:14
5.2.3. Enabling Multicast address family under BGP for an instance
To define the multicast address family under BGP for the instance, enter the following commands:
admin@leaf: cfg> set instance ip2vrf protocol bgp address-family ipv4 vpn-multicast
When the address family IPv4 multicast is enabled, all the VPNv4 routes which are exported from this instance will have a new extended community (rt-import) added.

5.3. Enabling MVPN Address Family and Peer Group
5.3.1. Enabling the MVPN address family under default BGP
