Been trying to figure this one out for a while now.
HQ has two internet connections. Each with a different ISP in two different buildings. The two buildings are connected via SM Fiber. SG 310 terminates each internet connection.
I have a remote office that has a single connection to the internet on an SG210 that needs to establish a S2S VPN to each of these remote HQ 310s so that if one of them goes down, the second tunnel picks up and they can access the servers. But what happens is the remote 210 sees it has a connection already going to the primary 310 and will not enter in the route to the backup 310 as it states there is a route overlap (expected). So, is there a way to have one VPN dormant and the other active and then flip if there is an outage at HQ?
Thanks!
