Tunnel interface not up

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

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

1. To resolve the problem:

   • Use the display interface command to verify that the physical interface of the tunnel is up. If the physical interface is down, check the network connection.

   • Use the display ipv6 routing-table or display ip routing-table command to verify that the tunnel destination is reachable. If the route is not available, configure a route to reach the tunnel destination.

2. If the problem persists, contact Hewlett Packard Enterprise Support.
