Members of an as-set are aut-nums and as-sets. However, a route-set members could be prefixes, other route-sets as well as aut-nums and as-sets. In such cases an aut-num defines the set of routes that are originated by that AS and an as-set defines the set of routes that are originated by the ASes in that as-set. > The reason I ask is that we are migrating a customer onto our network and whilst renumbering we will be advertising there assigned blocks from another provider. We currently use as-set's to depict our announcements to peers/providers so would like to add these to our as-set using a route-set object without having to replace our as-set object with a route-set object for our peer/provider announcements. > > Thanks, > Adam Regards, Andrei Robachevsky DB Group Manager RIPE NCC
