Can the experts help me in understanding this? I have 2 sites (A & B) connecting through a MPLS network. A can ping B. But B cannot ping A. Why? If A can ping B then B should have a route back to A. Correct?
I checked the BGP route on my two routers and they have a route to each other. When I do the traceroute to A from B router, I see that it stops at the 3rd hop, I believe that is the PE MPLS router.
