Joseph--
While perusing your router configs, I noticed that router A has the
following route setup:
ip route 172.16.10.0 255.255.255.0 172.16.20.2
The 172.16.10.0/24 network is directly connected to router A, yet this route
statement tells it to forward traffic bound for that network to router B...
This appears to be incorrect..
Furthermore, there is no need to set up static routes on a router for
networks that are directly connected since they are already known by the
router. In the example that you show, I can see no reason to add any routes
other than a default gateway on each of the routers.
Hope this helps some.

chris,
try to find out which router is using dce, do show controller in both
routers or show int serial. then do show clock rate, the dce should be
configured with the clock rate.
that's all i can think off right now.
regards,
