Does Cisco's IPSEC solution support backup tunnel.
Here's the setup/requirment. Remote site has one Internet connection. There are 2 host sites - Site A & B. VPN tunnel between remote and host site A should be up always as long as there's interesting traffic. The tunnel between the remote site and host site B should only come up only if the primary tunnel goes down.
Hi guys, I have a very similar setup and am facing some issues with the backup peer.
What I have is a Host ASA ->Link Load Balancer > Remote Router
the remote router is configured with two peers. The first peers works great, SA is formed and traffic flows. When the first peer goes down, the remote router can reach the secondary peer but cannot form an SA.
Before blaming the loadbalancer for this I just wanted to hear you thoughts on other possible problems.
We are using pre-shared keys for auth. and they look good on both ends.
