Inspired by discussion on "Announce less specific prefix in routeserver environment for upstream purpose (Message-ID: <4EEB4448.7070007@de-cix.net>) I would like to air the idea to modify the behaviour of BIRD as a route server. The idea of a route server is that it "... reduces modifications to advertised route attributes to be transparent (for example does not prepend its AS number to AS PATH attribute and keeps MED attribute)." However in case that there is a BGP speaker (gateway GW ) which is in the same ASN as the RS it is at least necessary to add the own ASN when announcing prefixes originating in the ASN. Hence I would like to propose to modify do not prepend own AS number to do not prepend owwn AS number except for prefixes learnt from iBGP Does that make sense?
