EIGRP (and the IGRP) are Cisco proprietary, and I've not seen any sort
of implementation on non-Cisco hardware. However, Cisco routers can
easily work with open routing standards (RIP, OSPF, BGP) and distribute
routes to/from those to/from EIGRP (and well, if planned carefully).

I've played a lot with Linux routing in my Cisco lab, and have found
that Zebra is very flexible. Zebra provides a very Cisco-like interface
(handy for those doing self-study), and fully supports:

* RIP (v1, v2)
* OSPF (IPv4, v6)
* BGP (IPv4,v6)

gated also supports various protocols, but is under a more restrictive
license. I've opted for Zebra for my use, but gated is highly respected.

If you can describe more fully what it is you're trying to do, perhaps
we can provide better information. If you're trying to use Linux to
route in an existing enterprise using EIGRP, you're unlikely to get them
to change just to accomodate you (though you can try :), so doing
redistribution on the Cisco router bordering your Linux world is
probably a good bet.

If you're interested in Cisco-Linux routing, you may be interested in
our little OpenWISP project (distributed routing lab). Serveral of us
doing Cisco self-study have formed a BGP/routing cooperative. Details
