Configuration Examples for IP Multicast Routing
Example: Configuring an IP Multicast Boundary
This example shows how to set up a boundary for all administratively-scoped addresses:
Device(config)# access-list 1 deny 239.0.0.0 0.255.255.255
Device(config)# access-list 1 permit 224.0.0.0 15.255.255.255
Device(config)# interface gigabitethernet1/0/1
Device(config-if)# ip multicast boundary 1

Example: Responding to mrinfo Requests
The software answers mrinfo requests sent by mrouted systems and Cisco routers and multilayer devices. The
software returns information about neighbors through DVMRP tunnels and all the routed interfaces. This
information includes the metric (always set to 1), the configured TTL threshold, the status of the interface,
and various flags. You can also use the mrinfo privileged EXEC command to query the router or device itself,
as in this example:
Device# mrinfo
