I have one router with two BGP neighbors, both in same AS. Using a prefix-list, I need to distribute some of the routes learned from one neighbor onto another. All prefix-list, access-list ect command are in place. Of course, it's not working. Can anybody give me a hint of what I'm missing, thsi is what I have so far
I do not understand what you are trying to do. If you learn a prefix from a neighbor in AS 209 and then advertise that prefix to another neighbor in AS 209 they will reject the advertisement because their AS number is already in the AS path. This is the basic loop prevention mechanism of BGP.
If this does not answer your issue then perhaps you can clarify what you are trying to do.
I should have explained, each of the neighbors point to a distinct MPLS cloud. My carrier gives them the same AS which is confusing. I agree about loop prevention, but since one cloud can not communicate with another, I thought there was a way around it. guess not.. it's a unique situation,,
The AS209 situation can work if you configure the router (Qwest CG1) with the allow local-as in feature. If it still does not work then maybe you need to review the prefix-list MRI that you are making. You can do the same with the distribute list as well.
