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.
