Hi,
Just a quick question as I feel I am banging my head against a brick wall here: is it actually possible to redistribute eBGP into EIGRP? I'm getting external BGP routes advertised across our MPLS, and I really need to stick them into EIGRP. If it is definitely possible I will post configs etc and explain in more detail!!!
Many thanks,
J

Redistribution of BGP in to EIGRP (IGP) is possible.
command is as below,
#router eigrp as#
#redistribute bgp as#

Thank you, this is what I have already. Do you have an experience of it working?
Here's what I have:

And the same for the others. But these routes do not make it to the EIGRP topology table (there are no entries for these networks).

I just figured it out; I needed a default-metric configured.
Yay me! :)

You need to configure a default-metric for routes being redistributed into Eigrp. The routes are otherwise not redistributed.
router eigrp 1
default-metric 10000 10 255 1 1500
or
route-map redistribute-bgp-route-to-eigrp permit 10
match ip address 92
set metric 10000 10 255 1 1500
