I have seen plenty of route redistribution scenarios where the default route gets injected into the other IGP's. When this happens (assuming it's not desired) you can filter it out on your redistribute line. For example:
ip prefix-list DEFAULT permit 0.0.0.0/0 ! router eigrp 2496 redistribute rip metric 1000 1 255 1 1500 route-map NO-DEFAULT ! Route-map NO-DEFAULT deny 10 Match ip address prefix-list DEFAULT Route-map NO-DEFAULT permit 90 The best thing you can do is lab this up and see what you find. That's the only way to learn! Cheers!

All, Please, little help... I wanted to confirm if my assertion is correct. the route (default route) generated by "default-information originate" command from one IGP protocol will not be used by another IGP protocol if the IGP is the only running IGP in the neigbor router. For instance: RtrA = runs rip and eigrp RtrB = runs only eigrp RtrA is performing mutual redistribution between rip and eigrp. Perfect eigrp adjacency is formed between RtrA and RtrB. in RtrA (under router rip) rip has d"efault-information originate" and eigrp did not. Would RtrB has default route that rip will creat in RtrA.
