Cisco Bug: CSCvu57850 - OSPF: Process exception and restart during ospf session flap
Sep 02, 2020
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: OSPF process exception and restart Conditions: This is only applicable when OSPF is enabled for Segment Routing. The condition is triggered by a rare timing condition when one of the router's stale (i.e. previously purged) Extended Prefix or Link LSA is received by the router. Such a scenario may happen with high scale and route/topology churn. E.g. this was seen during test on an OSPF ABR, during OSPF session flap and route churn There were ~20K (~20K prefix SIDs) nodes and ~40K OSPF routes in the topology.
