A snippet from an earlier mail by Robert.. How to control the amount of vpnv4 routes on Inter-AS ASBR -> (the worst you can do is to play with dummy vrfs !!!) Recommendations: A) Have a special single bgp community for exportable to inter-as peer vpnv4 routes - you set the filter once on ASBR and done. B) Do the bgp inbound filetering on receved bgp vpnv4 routes This is the most scalable approach..

I know that exists ORF and (now) regular expression for RT but it can become low controlable (ORF solution) or RT provision too complex. Is any SP have this kind of issues? Also what can I do if for example, a have more one intra-as session to the same as provider and I want to control the advertisement of the preffix in each session? By this time the way that I know is to filter based in RT or normal community. Any more ideia?
