Cisco Bug: CSCuo75711 - Flooding after LC reload with port-down flush disable/arp purge-delay
May 13, 2020
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Symptom: After LC reload, ASR9000 floods unicast packets on l2tranport interfaces under bridge-domain even if "arp purge-delay" and "port-down flush disable" are configured and some LCs keep MAC addresses and ARP entries. Conditions: ASR9000 is running with L2VPN configuration and terminates some vlans with L2transport interfaces. "arp purge-delay" under BVI and "port-down flush disable" under Bridge-Domain are configured so that ARP entries are not cleared.
