IPv4 point-to-point GRE tunnels
Displaying multicast protocols and GRE tunneling information
The following show commands display information about multicast protocols and GRE tunnels:
• show ip pim interface
• show ip pim nbr
• show ip pim mcache
• show ip pim flow
• show statistics
• show ip mtu
NOTE
All other show commands that are supported currently for Ethernet, VE, and IP loopback interfaces,
are also supported for tunnel interfaces. To display information for a tunnel interface, specify the
tunnel in the format tn <num>. For example, show interface tn 1. In some cases, the Ethernet port
that the tunnel is using will be displayed in the format tn<num>:e<port>.
The following shows an example output of the show ip pim interface command. The lines in bold
highlight the GRE tunnel-specific information.
