If the number of prefixes are small, and your on Cisco gear, take a look at IP SLA as an option for manipulating static routes. Basically it'll allow you to setup a probe, and based on the result of the probe, dynamically populate a given static route in the routing table or not. David.

The goal is to withdraw the prefixes should any part of the connection go down. Unfortunately router1--router2--firewall is part of a production setup and not easily changed. The idea is really to have something like this (ideally without router2): router1-router2-firewall-router3 | | router4-firewall-router5 I just wanted to check if I'm missing some knowledge about redistributing BGP into EIGRP. It appears that there is really no way to manipulate next-hop value. (no ip next-hop-self eigrp 1 is not really an option because there are many more prefixes coming from other routers that are being redistributed to router2 from router1) I will see if the network will allow BGP on router2. That seems to be the only clean solution for this. On Mon, Apr 18, 2011 at 9:25 PM, David Swafford <david () davidswafford comwrote:What's the real goal behind this?

Is there a way to advertise an EIGRP route with next hop of router3 (or firewall for that matter) rather than router1 which is what EIGRP doesbydefault Thank you in advance for advice. -- Andrey Khomyakov [khomyakov.andrey () gmail com]-- Andrey Khomyakov [khomyakov.andrey () gmail com]
