Haven't seen this before:
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
All other routers have something like:
Gateway of last resort is 10.22.129.254 to network 0.0.0.0
Does 0.0.0.0 to network 0.0.0.0 suggest that this router will broadcast anything it doesn't recognize?

If I read this correctly, and based on your comments, 0.0.0.0 says to send all unknown destinations out the Null0 int? In other words, drop the packet?
Thanks again.

Is the router redistribuing static routes into EIGRP to inject the route to null 0 into EIGRP?The only easy day was yesterday!
