Change "ip route 10.0.0.0 255.0.0.0 Async1" to "ip route 0.0.0.0 0.0.0.0
Async1 250"
This is known as a "floating static" because you have now put a "250" metric
on it. It will only be used if the other default route is down. Not sure
if this will fix you problem, as I am not to familiar with X.25 and not how
your routing is engineered. I changed the route to a default on the static
because in order for a floating static to work, there must be the exact
route (with a better metric) in the routing table during normal operation.
If you are receiving a "10.0.0.0/8" route via EIGRP when the X.25 is
working, use "ip route 10.0.0.0 255.0.0.0 Async1 250" instead. I hope this
at least points you in the right direction.
As an FYI, my company is also using Ravens with CDMA, except that in our
configuration we use PPP on the serial link to the Raven, and VPN tunnels
that terminate on frame-relay connection. This configuration is much
simpler to configure and troubleshoot.
