2.9.3 Example for Configuring IGMP Snooping SSM Mapping
Networking Requirements
On the network shown in Figure 2-4, IGMPv2 is run on Switch and Host 1 and Host 2, and
IGMPv3 is run on the last-hop router Router A on the multicast source side. Switch A is the
S7700 device. GE 1/0/0 on Switch A is connected to Router A and GE 1/0/1 on Switch A is
connected to a switch directly connected with users. GE 1/0/0 on Switch A is a static router
interface and GE 1/0/1 is statically added to multicast group 224.1.1.1. GE 1/0/0 and GE 1/0/1
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.
