Dear Colleagues, I have a simple question about route-set objects. <--RFC2622--> ... 5.2 route-set Class The attributes of the route-set class are shown in Figure 12. The route-set attribute defines the name of the set. It is an RPSL name that starts with "rs-". The members attribute lists the members of the set. The members attribute is a list of address prefixes or other route-set names. Note that, the route-set class is a set of route prefixes, not of RPSL route objects. ... </--RFC2622--> 1/ What is the reason that a route-set member can not be an aut-num or as-set object ? Because some registries allow this: route-set: RS-AS101-TO-ABILENE descr: routes that Abilene should accept from AS101 members: AS73, AS11808, AS7774, AS3807, AS13476, AS11995, AS14077, AS13476, AS11964, AS11827, 131.107.151.0/24, 131.252.0.0/16, 134.39.60.0/24, 161.55.0.0/16, 168.156.80.0/20, 168.156.96.0/19, 192.35.180.0/24, 192.46.80.0/24, 198.107.144.0/21, 198.32.40.0/24 admin-c: UW-NOC tech-c: UW-NOC mnt-by: MAINT-AS73 changed: aracine@cac.washington.edu 20010426 source: RADB 2/ Means the last phrase that there are no necessary is to existence of a related route object ? cheers frank
