I see that Alexander V. Chernikov wrote a patch to implement route aggregation back in 2012, and Ondrej Zajicek was planning on merging it with some changes: http://bird.network.cz/pipermail/bird-users/2013-January/003337.html However, it does not look like this was ever actually merged, and the latest version of the patch ("Version 7") seems to be missing from the mailing list archives. Does anyone know where I can find the latest version of this patch? Is there any chance this patch will ever be merged? Thanks! -Paul
