Redistribution of BGP routes into EIGRP

Hi there,

I have two routers running an EBGP session between AS65200 and 65100. AS65200 contains a small EIGRP network (EIGRP2), and AS65100 contains a large EIGRP network (EIGRP1).

I am trying to redsitribute the routes advertised by the BGP speaker in AS65200 into EIGRP2, which is running on the second BGP speaker in AS65100. Config as below.

router eigrp 1

redistribute bgp 65100

network x.x.x.x

no auto-summary

!

router bgp 65100

no synchronization

network x.x.x.x mask 255.255.248.0

neighbor x.x.x.x remote-as 65100

neighbor 192.168.27.2 remote-as 65200

neighbor 192.168.27.2 ebgp-multihop 255

neighbor 192.168.27.2 default-originate

no auto-summary

For some reason, the BGP routes do not get redistributed into EIGRP1. Although, with the similar config, I can get EIGRP2 to redestribute into BGP.

Any help on this would be great,

best regards,

Daniel,

Re: Redistribution of BGP routes into EIGRP

Daniel,

The BGP routes most likely are not making it into EIGRP 1 due to no metric for the BGP routes being specified. Try something like this:

conf t

router eigrp 1

redistribute bgp 65100 met 10000 100 255 1 1500

Now redistributing (unthrottled) fom an EGP (BGP) into an IGP (EIGRP) is not recommended at all. If your BGP AS is a transit for both sites it would be much better to leak only a default or specific routes you need to make communication occur.

Hope this helps,

Don

Re: Redistribution of BGP routes into EIGRP

Doesn't EIGRP just use its own metric if none is specified?

How could I leak specific routes from BGP into EIGRP?

Sorry, but I am fairly new to BGP

Thanks for your response

Daniel,
