L2L tunnels between three sites with ASAs
Posted on 2013-11-11
I am in the planning stages for a 3 site deployment where I would have Sites A, B, C. Site A is the main site and sites B and C will access internet through Site A.
I want all traffic other than local to be routed through the main site (A) however, site B needs to access 2 servers at site C and I would rather route that traffic on a tunnel between B and C.
My question is.... how can I tell the ASA to send traffic for x.x.x.x and y.y.y.y to tunnel BC and everything else to tunnel AB?
I am a little confused by this setup. Basically I would setup interesting traffic for tunnel BC to be x.x.x.x and y.y.y.y but since tunnel AB will route everything else, what would I set that up to be?
Site B===============Site C
