3.8 Troubleshooting Tunneling Configuration
Symptom
: After the configuration of related parameters such as tunnel source address,
tunnel destination address, and tunnel type, the tunnel interface is still not up.
Solution
: Follow the steps below:
1) The common cause is that the physical interface of the tunnel source is not up.
Use the
display interface tunnel
or
display ipv6 interface tunnel
commands to
view whether the physical interface of the tunnel source is up. If the physical
interface is down, use the
debugging tunnel event
command in user view to view
the cause.
2) Another possible cause is that the tunnel destination is unreachable. Use the
display ipv6 routing-table
or
display ip routing-table
command to view
whether the tunnel destination is reachable. If no routing entry is available for
tunnel communication in the routing table, configure related routes.
