Hi Thomas,
Thanks for going over the new version so quickly.

Hi Suresh.
Thanks for the revised document. It is much clearer now.
Some followup questions.
1) in Figure 1, it would help to explain whether everything to the
left of the edge router is in the same "broadcast domain". I.e, all
nodes attached to the network can send packets directly to each
other.
The nodes attached to different subscriber lines cannot directly send
packets to each other. They need to talk through the edge router.
2) What is the address assignment model. Is the entire left part of
the network one IPv6 link, with each node having an address out of the
same prefix? It would be good to more clearly identify what is an
individual customer. I assume that the Host/RG is a "customer".
Yes. Each customer will get different IPv6 prefixes. They will not share
prefixes.
Also, what on-link prefixes are assigned? Is the intention that
traffic between (say) Host1 and Host2 (behind differnet RGs) go
directly to each other, or does such traffic need to go through the
Edge Router?
All traffic needs to go through the edge router. There is no direct
host-to-host communication allowed between different subscriber lines.
3) For customers, do they all get addresses out of the same prefix? Or
do they get differnet prefixes? I guess the key question I'm asking is
why does the edge router need to know what circuit a given RG is on
when responding to an RS. What informaiton does the RS return that
depends on that circuit ID or that might vary from one RG to another.
Each customer needs to get a different prefix. The information that
differs based on the Line ID is the prefix that gets inserted into the PIO.
Thanks
Suresh
