Cisco Bug: CSCum14732 - Prefix with Different RNH but same NH being deleted in RIB
Jan 22, 2014
- Cisco Nexus 7000 Series Switches
Known Affected Releases
Symptom: This only applies to route/path with v6 next hop. When BGP attempts to update a route/path in RIB with a different RNH but is resolved by BGP using the same next hop, the route in RIB will be unexpectedly deleted. A 'clear ip route <prefix>' or 'restart bgp' will recover the missing route. Conditions: This happens in multi-hop and/or ebgp/ibgp scenarios where the remote ebgp nexthop will be passed to ibgp peers. When ebgp nexthop changes, update will be sent to the ibgp peers.
