Displaying GRE tunneling information
This section describes the show commands that display the GRE tunnels configuration, the link
status of the GRE tunnels, and the routes that use GRE tunnels. To display information about
multicast protocols and GRE tunnels, refer to “Displaying multicast protocols and GRE tunneling
information” on page 1062.
To display GRE tunneling Information, use the following commands:
• show ip interface
• show ip route
• show ip interface tunnel
• show ip tunnel traffic
• show interface tunnel
• show statistics tunnel
The following shows an example output of the show ip interface command, which includes
information about GRE tunnels.
Brocade# show ip interface
