Configuring Multicast VLAN Routing With IGMP and PIM-SM
This example describes how to configure a Dell Networking N-Series 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. 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 46-54. 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.
