22.2.3 Multicast Example
The minimal configuration has one LAN interface with igmp proxy enabled and one LAN
interface with igmp proxy enabled. A LAN interface will receive IGMP messages from
clients and will forward traffic related to the clients’ groups accordingly. A WAN interface
will forward IGMP messages to the WAN for the relevant groups, and listen for multicast
traffic from that group.
First, enable igmp-proxy mode from the data configuration mode:
configure data
ip multicast-routing
mode igmp-proxy
