EIGRP default route injection

prafuljaded · ‎12-14-2005

Hi All,

Any one knows how to inject default routes in EIGRP to a particular EIGRP neighbor. Lets say we have router A,B and C. I want to inject an EIGRP default route from A to B and not to C.I know its possible in OSPF.

Thanks,

Praful

Hi Praful,

There are two ways to inject a default route into EIGRP: redistribute a static route or summarize to 0.0.0.0/0.

Summarizing to a default route is effective only when you want to provide remote sites with a default route. Since summaries are configured per interface, you do not need to worry about using distribute-lists or other mechanisms to prevent the default route from being propagated toward the 3rd router.
