6.5.25.BASE

Description (partial)

Symptom:
When xconnect is configured on L2 bundle. Load balancing will not work, all the traffic go (egress) over single  member link.
When line card with NNI link is reloaded, sometimes when fia-cfg (fatpw lb config) notification has come before even the interface was created and so it is failing to get applied on the interface. So Interface is getting created with ?load-balance forwarding? itself instead of ?load-balance terminated?.

Conditions:
When NNI (core) link line care is reloaded.
