Hi Ole So I see two tracks here, as I noted last year in BBF. 1. You sent the RA periodically multicasted for the defautl router address advertisement. In this you can also multicast a Prefix as would be the case in some situations, i.e. hotspot deployments connected over a TR-101 network. 2. The Edge node waits for the RS before sending the RA to trigger sub rules and allocate an IPv6 Prefix specifically for this identified host.
Reality is this will be used by numerous Fixed Service Providers whom have an N:1 VLAN model and will not change this because of IPv6 :-) On the periodic RA's I agree for the default router address but for PIO options that is configurable ;-)....i would not like all my hosts on an Edge node to be multicasting the same prefix to thousands of sub lines....hmmm!

SLAAC works with periodic RAs. so in the above scenario SLAAC would work, it would just take a little longer. if what is proposed in rs-mark is only to use 'triggered by RS' unicast RA's then I think you are breaking how SLAAC is intended to work. if you _do_ send periodic multicast advertisements even without PIO options, you should be OK I think. cheers, Ole -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
