failover of VPN tunnels
Posted on 2014-12-29
We have several external sites connected via site to site vpn tunnels using 5520 ASAs. On the primary asa where I’m at, we have tunnels that go to customer external sites to monitor certain devices. We have over 40 tunnels to customer sites. There supposed to be some kind of replication mechanism on the primary asa that if the primary asa fails, the asa at the other site, will pick up and we will be able to monitor everything form that asa until we fix the primary. (failover)
I have no idea what that failover looks like and I need to do find out how it works and how its configured. How can I go about finding out? I see on the other asa there is a tunnel to me and I know that’s active. Can anyone give suggestions or help me figure this out?
