WAN Routing Question
I'm having a mental block on this one...help me out.
I have 2 sites with a NSA at each.
Site A has 2x WAN connections setup in Failover/LB with X1 as the live and X2 as the failover.
I have a VPN between the two sites (tunnel interfaces). I need the VPN at Site A to use X2 as its preferred connection to reach Site B. I've achieved this by binding the VPN to X2. The problem with doing this, is that if X2 fails, the connection won't automatically failover to X1.
My question is, how can I achieve redundancy whilst preferring the failover (X2) connection on the VPN? I can't have another tunnel interface using X1 as you're not allowed multiple tunnel interfaces with the same target address...
