Re: eigrp set next hop

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.

What's the real goal behind this?  What your describing sounds like a

Hi nanog

I need to advertise EIGRP route with a different next-hop value than self

Due to how the connections are setup, I have to run BGP between two peers
that are 3 hops away from each other.

router1--router2--firewall--router3
I'm running EBGP between router1 and router3
router1 is redistributing into EIGRP that's running with router2

The problem is that now router2 thinks that router3 routes are reachable
via
router1 so I have myself a route loop.

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 does by
default

Thank you in advance for advice.
