SSM Multicast Forwarding (IGMPv3 Host Alternative)
The following is an alternative procedure for SSM multicast forwarding by configuring the IGMPv3 host on the network
side.
To Configure Network to Cable Data Forwarding Using an IGMPv3 Host on an NSI
1.
Enable the IGMP router/querier on the cable-mac. Default is IGMPv2.
configure interface cable-mac <mac>ip igmp
2.
Enable the IGMP router/querier on the cable-mac for IGMPv3.
Note: This is required for MDF-enabled cable modems.
configure interface cable-mac <mac> ip igmp version 3
3.
For each DS cable interface that needs to carry multicast traffic, a proxy interface must be assigned for receiving the
multicast traffic:
configure interface cable-mac <mac> ip igmp proxy-interface <ten>gigabitethernet
<slot>/<port>[.<subif>]
4.
A backup proxy interface may also be configured:
configure interface cable-mac <mac> ip igmp backup-proxy-interface <ten>gigabitethernet
<slot>/<port>[.<subif>]
5.
Configure the IGMPv3 host on the network side interface:
configure interface <ten>gigabitethernet 17/<port> igmp host-version 3
configure interface <ten>gigabitethernet 18/<port> igmp host-version 3
