Symptoms

When the configuration is changed from interface tunnel to policy based tunnel, tmm crashes. Most likely this is a timing issue where the pnh is not updated while the policy was updated. So the policy_type (policy_interface vs policy_ipsec) mismatched.

Impact

Traffic disrupted while tmm restarts.

Conditions

Traffic passing in the background and change the configuration from interface tunnel to policy based tunnel.

Workaround

No workaround

Fix Information
