EIGRP Default Networks V.S. Static Default Gateway
Posted on 2006-06-15
I am not getting something here and I hope you can help me...
Default network - ROuter says if I dont know where to send you i send you to this SPECIFIC ROUTER interface, soo...
ip route 0.0.0.0 0.0.0.0 192.168.1.1 says "send it all to 192.168.1.1" if I dont know where to go.
That makes PERFECT sense to me....
ip default-network 192.168.1.0
How the heck does it know which router on this network to send it to? Is it selecting the first network route in the list, and using the router specifed there?
i.e. if i have two routes : IP ROute 192.168.1.0 255.255.255.120 192.168.1.1
IP route 192.168.1.0 255.255.255.120 192.168.1.254
So in this case it could select either depending on whats avilable etc??
So if I have a network righ now that is, let's say:
IP route 0.0.0.0 0.0.0.0 10.0.0.1 (class A just for fun)
Now it would be:
ip default network 10.0.0.0.0 255.255.255.0
I think what really confuses me is where to put the default network statment. In other words you put a static Default route on every router. Do I just need to put this on one router and all the others will pick it up?
