Displaying GRE tunneling information
This section describes the show commands that display the GRE tunnels conguration, the link status of the GRE tunnels, and the routes
that use GRE tunnels.
To display GRE tunneling Information, use the following commands:
• show ip interface
• show ip route
• show ip interface tunnel
• show ip tunnel trac
• show interface tunnel
• show statistics tunnel
The following shows an example output of the show ip interface command, which includes information about GRE tunnels.
device# show ip interface
Interface IP-Address OK? Method Status Protocol
VRF
Tunnel 1 101.1.1.1 YES NVRAM up up
red
Tunnel 3 89.1.1.1 YES NVRAM up up
default-vrf
For
eld denitions, refer to Displaying IP interface information on page 127.
Syntax: show ip interface
The show ip route command displays routes that are pointing to a GRE tunnel as shown in the following example.
device# show ip route
