I am correcting myself. I gave the wrong version on the previous email. 

 On one side is BIRD v2.0.11 and on the other side is CISCO ASR.

However, we have observed an unexpected behavior: after the BIRD daemon successfully establishes the BGP connection, router sends a BFD Admin-down message and requests a new BFD session. This action by router leads to BIRD transitioning to a BFD down state and tearing down the previously established BGP session.

Sorry for late reaction. That is BIRD 2.0.11 on both sides?
