Opened: Aug 16, 2017
Severity: 3-Major

Symptoms

Using a multicast VXLAN tunnel without a proper route associated with the tunnel's local-address may cause a TMM crash.

Impact

The TMM crashes and traffic is disrupted.

Conditions

When the following conditions are met: - No route is associated with the tunnel's local-address. - A selfip address is assigned to the tunnel. Then, a connection using the tunnel may cause a TMM crash. Note that the user can use the TMSH command "show net route lookup <address>" to check if there is a route associated with the tunnel's local-address.

Workaround

Make sure that there is a route associated with the tunnel's local-address, before using the tunnel.

Fix Information

The TMM no longer crashes.
