Cisco Bug: CSCta05722 - BFD over BVLAN stale complink session
May 16, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: Basic issue is that there are stale complink session objects hanging around (bfd_db_comp_link_session_t). This can prevent any further BVLAN sessions configured to not come up properly. Conditions: Looking closely at the code, it appears that bfd_agent can fail complink session deletion if right timings are hit between complink deletions and session deletions in thread 1 and thread 3 (due to session database, session lock, and complink lock).
