Cisco Bug: CSCsz01370 - MSDP flaps on AT&T lab routers due to blockage on ARM
May 09, 2018
- Cisco Carrier Routing System
Known Affected Releases
None Symptoms: MSDP sessions flap after an NDSC RP failover. This was seen with and without Inactive peers. Conditions: During an NDSC RP FO, the routes to the MSDP peers might change (move to max-metric and come back to normal metric, for example). In a Multi-Chassis (4+1, in this case), MSDP is blocked for a long time on ARM/sysdb_mc and that causes the Established sessions to flap. The failure has been seen only in a Multi-Chassis system.
