Oct 19, 2016
- Cisco IOS
Known Affected Releases
Symptom: With IPSEC and RRI (reverse route injection) enabled, When an IP address changes and we have a situation where the remote has more than one SA pair that is sourced from the same protected subnet, it may be possible to maintain more than one route to two different next hops. This sitiuation will remain until all SA pairs are reset to the new peer address or they timeout. The result would be that there may be some packet loss as the older, now invalid route is used. Condition: 1)RRI with ip address change 2)two or more SAs to the same remote proxy.
