Symptoms

Running 'tmsh show net route lookup 224.0.0.1' results in TMM crash.

Impact

Traffic disrupted while tmm restarts.

Conditions

Running the following command: tmsh show net route lookup 224.0.0.1

Workaround

There is no workaround other than avoiding avoid route lookups of multicast destinations from tmsh. It should be possible to use 'ip route show' instead. tmsh still should work for unicast routes.
