Table 13: Commands for Monitoring IP Multicast Routing
PurposeCommand
Queries a multicast router or multilayer
switch about which neighboring multicast
devices are peering with it.
mrinfo [hostname | address] [source-address | interface]
mrinfo { [hostname | address] | vrf }
Displays IP multicast packet rate and loss
information.
mstat source [destination] [group]
mstat { [hostname | address] | vrf }
Traces the path from a source to a
destination branch for a multicast
distribution tree for a given group.
mtrace source [destination] [group]
mtrace { [hostname | address] | vrf }
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:
Switch(config)# access-list 1 deny 239.0.0.0 0.255.255.255
Switch(config)# access-list 1 permit 224.0.0.0 15.255.255.255
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# ip multicast boundary 1
