To display the number of PIM neighbors discovered, use the show command described in the following example.

Router# show ipv6 pim neighbor

Neighbor Address Interface Uptime Expires DR pri Bidir

FE80::1:1:3 FastEthernet4/10 04:27:15 00:01:23 1 B

To display the information in the PIM topology table in a format similar to the show ip mroute command, use the show command described in the following example.

Router# show ipv6 mroute
