Currently running ADVPN to connect our branches to our core. I've added ADVPN-BACKUP for branches which uses the 2nd ISP in our core. It connects fine and can access resources in the core. What it can't do is communicate with other sites that are on the primary. ie. ADVPN-MAIN cannot communicate with ADVPN-BACKUP and vice versa but both can communicate with the core just fine. I'd like to allow the branches to select either the main or backup based on latency so I need to get communication between the two of them. Is this a route or rule that I'm missing somewhere? I can post the relevant portions of the config if necessary.
