Abandoned SAs associated to an IPSEC tunnel
I'm wondering if this is SOP or something else. In Status -> IPSec I'm seeing several SAs between two IPs which I have a tunnel configured, but I have only one phase 2 defined. One pair of the SAs actually have traffic indicated while the rest are zero byte.
Site A is running 2.4.4p3 and, based on the logs, requested the recreation of all the SAs on the last REKEY event. Site B is running 2.4.2 and complied.
Is this normal for the protocol?
It's normal to see extra copies in there depending on how the negotiation/rekey happened. As long as your traffic is flowing and the tunnel rekeys when needed and keeps going, it's not worth worrying about.
