configure interface cable-mac <mac>.<subif> ip igmp proxy-interface <ten>gigabitethernet
<slot>/<port>
5.
Configure the IGMP backup proxy interface joins received on the cable-mac to an alternate network side interface if
the primary is down.
configure interface cable-mac <mac>.<subif> ip igmp backup-proxy-interface <ten>gigabitethernet
<slot>/<port>
6.
(Optional) Configure the IGMPv3 host on the network side interface if required for your system:
configure interface <ten>gigabitethernet 17/<port> igmp host-version 3
configure interface <ten>gigabitethernet 18/<port> igmp host-version 3
SSM Multicast Forwarding (PIM-SSM Alternative)
The following procedure supports SSM multicast routing using the PIM-SSM mode.
Configure Network to Cable SSM Data Forwarding
1.
Enable the IGMP router/querier on the cable-mac. Default is IGMPv2:
configure interface cable-mac <mac>.<subif> ip igmp
2.
Enable the IGMP router/querier on the cable-mac to IGMPv3:
configure interface cable-mac <mac>.<subif> ip igmp version 3
3.
Enable multicast routing:
configure ip multicast-routing
Note: PIM can only be enabled in the SSM node. Other PIM CLI provisioning is disallowed if multicast-routing is not
enabled.
4.
Configure PIM-SSM on the cable-mac as passive:
configure interface cable-mac <mac>.<subif> ip pim sparse-mode-ssm passive
5.
Enable PIM-SSM on the network interfaces:
configure interface <ten>gigabitethernet <slot>/<port>[.<subif>] ip pim sparse-mode-ssm
