L2 Multicast Configuration Examples
This section contains the following examples:
• Configuring IGMP Snooping
• Configuring MVR
Configuring IGMP Snooping
This example configures IGMP snooping on the switch to limit multicast
traffic and to allow L2 multicast forwarding on a single VLAN. The IP-
multicast traffic in VLAN 100 needs to be Layer 2 switched only, so the IGMP
snooping querier is enabled on the switch to perform the IGMP snooping
functions on the VLAN, if necessary. The switch can send queries even if it is
not the IGMP snooping querier and will use 0.0.0.0 as the source IP address.
This will not cause any disruption to the operation of external querier.
In this configuration, an IP-multicast router is not required.
The three hosts in Figure 25-36 are connected to ports that enabled for IGMP
snooping and are members of VLAN 100. Port 24 is a trunk port and connects
the switch to the data center, where the L3 multicast router is located.
