Configuring PIM-SM
Fixed Switch Configuration Guide 19-23
Figure 19-6 PIM-SM Configuration
Routers R1 and R4 Configuration
On Router R1, at the switch level, IGMP snooping is enabled globally and on the ports connected
to hosts. At router level (Level 3), the IGMP querier function is enabled on the device, and IGMP is
enabled on VLAN 2, which connects to hosts. IGMP is used to determine host group membership
on directly attached subnets. PIM-SM is enabled globally and on all interfaces. The underlying
unicast routing protocol is OSPF.
The configuration on Router R4 would be the same, but would use different VLANs, IP addresses,
and router ID.
