Known Affected Releases

5.1.2.BASE

Description (partial)

Symptom:
BFD packets which are supposed to be high priority packets are getting into the LP queue when the QOS policy is configured to a low policer value for a bundle interface with BFD over Bundle interface configured.

Conditions:
BFD sessions start flapping which brings down the bundle since BFD packets are not being received by the peer. This needs some changes in the PD code for CRS
