need to prevent redistributed eigrp routes sending via IBGP session.

[syjeon]

Hi,

first of all, pls, see the attached file that it depicts the diagram as well as problem description.

I thought that If I add tag when eigrp redistribute into bgp, then, I could use that tag value to prevent updating from peer iBGP session.

However, when I tested, 'set tag' was not working when I import eigrp reoutes into bgp. the error message was appreared like below.

% "rdeigrp2bgp" used as redistribute eigrp into bgp route-map, set tag not supported

So, I've tried to use 'community-value' when redistributed, so that I can use this value to select proper routes under conditional.

Can you look over my test result and give me more good idea to me to be archived as better solution.

Thanks.

Hello,

Yes, you are right - BGP has no tags. Community attributes replace them.

I think that for your current needs, your solution with the communities is the simplest and most straightforward. If it works for you, keep it.

Best regards,
Peter
