(DCE is connected to router 1)
but i cant ping one from the other can someone please help me
below is the IP route, IP interface, CDP neighbors
and running config from both my routers.

You aren't running any sort of routing protocol and you haven't specified any static routes. This means only router 1 will know about 172.16.12.0/24 and only router 2 will know about 172.16.11.0/24.
They will each know about 172.16.10.0/24 network since they are connected. You should be able to ping each side of the .10 /24 right?
add the following:
on r1:
ip route 172.16.11.0 255.255.255.0 172.16.10.2
or r2:
ip route 172.16.12.0 255.255.255.0 172.16.10.1

yea each router can ping the other routers serial ".10"
but neather one can ping the others ethernet ".12 and .11"
Im following a lab and it says i should be able to ping the ethernet of the other router.
I added the ip route and it works
now i just have to figure out what I just did
Thanks

You u should check clock rate on the router which is connected with DCE it should be 64000
