Troubleshooting tunneling configuration

Symptom

A tunnel interface configured with related parameters such as tunnel source address, tunnel destination
address, and tunnel mode cannot go up.

Analysis

The physical interface of the tunnel does not go up, or the tunnel destination is unreachable.

Solution

1. Use the display interface or display ipv6 interface commands to check whether the physical
interface of the tunnel is up. If the physical interface is down, check the network connection.
2. Use the display ipv6 routing-table or display ip routing-table command to check whether the
tunnel destination is reachable. If the route is not available, configure a route to reach the tunnel
destination.
Command
display interface [ tunnel ] [ brief [ down ] ]
display interface [ tunnel [ number ] ] [ brief [ description ] ]
display ipv6 interface [ tunnel [ number ] ] [ brief ]
reset counters interface [ tunnel [ number ] ]
