Command History
Modification Release

Usage Guidelines
The mrinfo command is the original tool of the multicast backbone (MBONE) to determine which neighboring
multicast routers or switches are peering with multicast routers or switches. Cisco routers have supported
responding to mrinfo requests since Cisco IOS Release 10.2.
You can query a multicast router or multilayer switch using the mrinfo command. The output format is
identical to the multicast routed version of the Distance Vector Multicast Routing Protocol (DVMRP). (The
mrouted software is the UNIX software that implements DVMRP.)
Examples The following is sample output from the mrinfo command:
