Symptoms

Permanent connections, such as those used between tunnel endpoints, can be deleted when the route to the remote endpoint is removed.

Impact

Conditions

-- Permanent connection, such as a tunnel. -- Routing updates, either from explicit static or dynamic routes, or modifying self IP addresses.

Workaround

Remove and re-add the affected connection: e.g., delete and re-configure tunnel.

Fix Information
