We've got two sites connected with MXs via MPLS (AT&T AVPN). This allows us to easily access resources between sites. MPLS routers are connect to MX's LAN ports. Both sites have internet connected to MX's WAN port. Sites have separate subnet addresses, and MX has static routes. I would like site B to be able to use site A's internet service if site B's local internet fails. I'm OK with manually switching it over. My guess is I would need to: Get AT&T to allow ALL traffic through their routers, across the MPLS (instead of just the few VLANS they have configured now) And, I would have to create a static routes in both MX's to allow ALL subnets through. Does this sound correct? Am I missing anything else?
