I've seen some (very.. some) subnet anycast out there.. I do not know (myself, which can be rather limited snapshot) a production network using other RFC5453 reserved anycast IIDs. > like most ipv6 magic, i think it is ignored and regular old ipv4-style > anycast is used. Sure and that is fine. What I am/was concerned about is that we do not walk over existing (standards track) RFCs. If these IIDs meanings and 'u' & 'g' bits get redefined/obsoleted/whatever.. fine but that must then be reflected in other RFCs that today are based on RFC4291 etc. The whole blob needs then be updated/obsoleted accordingly and with care. On this aspect I care about specification correctness - not whether something is actually deployed (yet). - Jouni > > randy > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > ipv6@ietf.org > Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 > -------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
