Hello I understood it that as small AS, you have small set of 'your' (or customers') prefixes (say 10) in prefix set which you want to export to all your peers and upstreams. If you have hundred of peers and few millions of global routes, you may want to avoid few 10E8 of route matching of that prefix set for export, when you can just have secondary table connected to master table by pipe with prefix set filter and containing these 10 routes, while peer BGP sessions could be configured to import to master table and export from secondary table (so only ~10E4 route processing would be done for export). It could be thought as a pair of separate unidirectional channels for import and export, connected to different tables. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
