could someone please explain the following to help me understand how it works??
I have 2 routers connected via a serial p2p link and configured with /30 ip's at both ends. If I connect to 1 router and ping its own local WAN interface, the ping request actually traverses the wan link to the B end and returns instead of just going internally directly to the wan interface. If I ping an ip on the remote router, the avg response time is say 90ms however if I ping the local wan interface the avg response time is about double at 180ms. I switched debugging on on this interface and confirmed it to be correct.
Any feedback would be helpful??
