Difficulty on the BGP routing issue. I have 2 routers, router A1 and router A2 are running in BGP for routing connection. Currently we setup a site to site VPN from router A2 to router B. Once the VPN connection establish, how to we connect to router B from router A1? Attached diagram below:-
It looks right. From this config, you'll be able to get to the shared subnet between A2 and B, but what's on the LAN side for B? You'll need to have a static address for that unless you're going to run a routing protocol. On Router B, you'll need a static route for A1 to point to A2 in order to get return traffic from A1 to B and back.
