Queries targets for multicast routing information.
This works by sending a DVMRP Ask Neighbors 2 request to the target and listening for DVMRP Neighbors 2 responses that are sent back and which contain local addresses and the multicast neighbors on each interface of the target. If no specific target is specified, the request will be sent to the 220.127.116.11 All Hosts multicast address.
This script is similar somehow to the mrinfo utility included with Windows and Cisco IOS.
