Description (partial)


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.

1)RRI with ip address change
2)two or more SAs to the same remote proxy.
