Description (partial)

Symptom:
'TUNNEL GLOBAL RSVD VLAN' may be deleted causing MPLS-TE packet loss

Conditions:
'TUNNEL GLOBAL RSVD VLAN' is suddenly removed on it's own, which causes recirculated packets (that would normally be sent to this vlan), to instead be sent to HWRL dest index 0x7F0A and dropped.  Dropped packets were forwarded via MPLS-TE over L3 Port-Ch.
