Static Router Port
Configuration
Network requirements
■ As shown in Figure 173. Router A, which acts as the IGMP querier on the
subnet, connects to the multicast source through Ethernet1/1/2 and to Switch
A (Switch 8800) through Ethernet1/1/1.
■ IGMPv2 runs on Router A and Switch A. IGMPv2 Snooping runs on Switch A.
Router A works as the IGMP querier.
