Description (partial)

The VPLS bit is not set in the flood VLAN LTL index which causes a traffic drop.

This symptom occurs under the following conditions:

* Have a port-channel with member links on different NP (say NP2 and NP1) and a physical interface on the same LC and NP (say NP2) to different neighbors, say PE1 and PE2 respectively.
* Shut down the member link of NP1.
* Remote shut the VLAN or access interface on PE2 (reached by  physical interface).
* The V-bit is not set and this affects the traffic towards PE1 (reached by port-channel interface).
