Re: [dhcwg] I-D Action: draft-ietf-dhc-dhcpv6-pd-relay-requirements-04.txt

Hi,

We’ve just posted an update to the draft with changes based on the AD’s review (thanks Éric).

The main changes are:

1, R-5 has been moved to R-2 as it is related to R-1.
2, R-3 (previously R-2) has the following text added (for consistency with the new R-2 requirement):

The delegating relay's ingress filter entry MUST use the same prefix length for the delegated prefix as given in the IA_PD.

3, S-1 has been reworded to remove redundant text:

To preserve active client prefix delegations across relay restarts, the relay SHOULD implement at least one of the	
 following:

In addition, there are a few small changes in the language for clarity.

Thanks,
Ian
