Troubleshooting tunneling configuration Symptom After the configuration of related parameters such as tunnel source address, tunnel destination address, and tunnel mode, the tunnel interface is still not up. Solution 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, check the network connections. 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. 152
