The following shows an example output of the show ip pim interface command. The lines in bold
highlight the GRE tunnel-specific information.

The following shows an example output of the show ip pim nbr command. The line in bold shows
the GRE tunnel-specific information.

The following shows an example output of the show ip pim mcache command. The line in bold
shows the GRE tunnel-specific information.

The following shows an example output of the show ip pim flow command. The text in bold
highlights the GRE tunnel-specific information.
Brocade# show ip pim flow 192.168.1.1

The following shows an example output of the show statistics command. The following statistics
demonstrate an example where the encapsulated multicast traffic ingresses a tunnel endpoint on
port e 1/1/2, egresses and re-ingresses as native multicast traffic on the loopback port e 1/1/4,
and is then forwarded to the outbound interface e 1/1/1.
