Symptom: IP connectivity over BDI fails after a link flap network event.
Conditions: This issue occurs intermittently with BDI enabled for IP/MPLS forwarding and
running VPN services over it. Adjacency failures are seen after couple of link flap events, which
impacts Layer3 forwarding over BDI.
Workaround: There is no workaround.
• CSCuh13883
