Monitoring IPv6 Multicast Settings

The commands in this sections display general information about the IPv6 multicast configuration on the router.

show ipv6 mroute

Use to display information about all or specified multicast forwarding entries.

Specify a multicast group IPv6 address or both a multicast group IPv6 address and a multicast source IPv6 address to display information about particular multicast forwarding entries.
