L3 Multicast Configuration Examples
This section contains the following configuration examples:
• Configuring Multicast VLAN Routing With IGMP and PIM-SM
• Configuring DVMRP
Configuring Multicast VLAN Routing With IGMP and PIM-SM
This example describes how to configure a PowerConnect switch with two
VLAN routing interfaces that route IP multicast traffic between the VLANs.
PIM and IGMP are enabled on the switch and interfaces to manage the
multicast routing. IGMP snooping is enabled on the VLAN interfaces to
control the multicast subscriptions within each VLAN. VLAN 10 is statically
configured as the RP for the multicast group.
The configuration in this example takes place on L3 switch A shown in
Figure 42-47. The red arrows indicate the path that multicast traffic takes. L3
Switch A is configured as the RP for the PIM domain, so it is in charge of
sending the multicast stream to L3 Switch B and L3 Switch C, and these
switches forward the multicast data to the hosts that have requested to
receive the data.
NOTE: PIM does not require OSPF specifically; static routing or RIP could also
be configured for unicast routing.
