Hi all!
I use bird2 (2.0.9) as RS for BGP prefix aggregation - several peers send me their prefixes, I aggregate them and send the result to the system. But there is an obvious issue - when peers send me the same prefix, BGP selects the best one and sends only that one. In this case, if prefixes had different communities, the result loses all but one. For example: peer 1: 1.1.1.1/32 1:100 peer 2: 1.1.1.1/32 2:200 peer 3: 1.1.1.1/32 3:300 If the last one was chosen, the result is 1.1.1.1/32 3:300 If there is any way to collect all communities and attach them to the chosen prefix (like this: 1.1.1.1/32 1:100,2:200,3:300), would anyone please tell me how to do that? Thank you, Valery
