Symptom
VPWS traffic is dropped when the L2xc program fails.
Main symptom:
! From the output "show l2vpn forwarding interface private location " you can see PD Fail traces:
+ show l2vpn forwarding interface be1001.2512 private location 0/0/CPU0

Conditions
NCS5500/NCS5700 - Multi NPU platforms.
! Conditions:
1 - AC should be a sub-interface belonging to a bundle-ether.
2 - The bundle-ether should have members belonging to different LCs/NPs.
3 - All the interface members of this bundle-ether, belonging to a particular NPU must be removed, while others remain. << Check the commit history.
Workaround
+ Remove and re-add sub-interface AC configuration.
Further Problem Description
Steps to repro:
1. Needs multinpu line card with bundle members on multiple NPU of the linecard
2. Configure bundle sub interface as AC.
3. remove all members from a particular NPU while member from other NPU remains.
4. Readd the member from the NPU where all member was removed.
