1.7.2 Example for Configuring IGMP Snooping SSM Mapping

Networking Requirements
On the network shown in
IGMPv3 is run on the last-hop router Router A on the multicast source side. Switch A is the
S2700 device. Eth 0/0/1 on Switch A is connected to Router A and Eth 0/0/2 on Switch A is
connected to a switch directly connected with users. Eth 0/0/1 on Switch A is a static router
interface and Eth 0/0/2 is statically added to multicast group 224.1.1.1. Eth 0/0/1 and Eth 0/0/2
both join VLAN 10 and IGMP SSM mapping is deployed on Router A.
It is required that IGMP snooping SSM mapping be configured on Switch A in the VLAN to
work jointly with IGMP SSM mapping. IGMP snooping SSM mapping also generates a mapping
between a multicast group and a multicast source. (*, G) information in IGMPv1 or IGMPv2
multicast data packets is then mapped to (S, G) information, providing SSM services for the
hosts running IGMPv1 or IGMPv2.
