Ian,
thanks!
[ian] Couple of changes to 4.5:
Old:
The Port Parameters Option specifies optional Rule Port Parameters
that MAY be provided as part of the Mapping Rule for CEs using the
MAP algorithm.
New:
The Port Parameters Option specifies optional Port Set information
that MAY be provided to CEs.
that looks fine.
Old:
When receiving the Port Parameters option with an explicit PSID, the
client MUST use this explicit PSID in configuring its MAP interface.
If the conveyed IPv4 address is not 32 bit-long, the option MUST be
discarded. The formula for this check is "prefix4-len + ea-len = 32"
and serves to ensure that the explicit PSID is only applied to
configurations with a completely formed IPv4 address.

what about keeping the old text with your change of s/MAP interface/softwire
interface/.
at least in theory LW46 could support IPv4 prefixes, or a new mechanism could
come along that did.

What about the following wording change:
Old:Allowed values are between 0 and 15, with the default value being 6.
New:
Allowed values are between 0 and 15. Default values for this field are specific
to the softwire mechanism being implemented and are defined in the relevant
specification document.
that looks fine. updated.
Good spot on the WKP exclusion. Before the lw4o6 draft was updated to reference
map-dhcp for configuration, the port configuration was described in
sun-dhc-port-set-option, which also stated that the WKPs should not be
assigned. This advice got lost when changing to reference map-dhcp. I’ll make a
suggested text update for the lw4o6 draft to fix this. Does that work for you?
yes, that would be good.
cheers,
Ole
On the WKP exclusion, you might point people to the last paragraph of
Appendix B.1 in draft-ietf-softwire-map.
