In addition to multicast configuration, this example includes commands to
configure STP and OSPF on L3 Switch A. STP is configured on the ports that
connects the switch to other switches. OSPF is configured to route unicast
traffic between the VLANs and PIM is enabled to rout multicast traffic
between the two VLANs. Since IGMP snooping is enabled by default on all
VLANs, no commands to enable it appear in the example below.
To configure Switch A:
1 Create the two VLANs. IGMP/MLD Snooping is disabled globally.
