I have 2 routers on a point to point network. When the user from the LAN try to trace to the core router (CR1) the trace stops on the router connected to his LAN. He cannot get past the serial interface on his router. However when I connect to his router I can ping the core router.
Attached is the running config of his router on his LAN.
From your post I cannot verify if this is the only router at the remote site. Does the trace indeed go to 192.168.2.2?
If not, the users default gw is probably misconfigured.
For the rest, is this a new config or has this already been working?
Normally you should also add the 192.168.2 network to eigrp also using: "network 192.168.2.0".
Without this, the other router (CR1) will not have a route for network 192.168.2.0.
