Default Gateway

mikearama

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?

Okay, I kinda get ya. So let me paste this router's entire sh ip route...

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.
