Re: Last Call: 'RPSLng' to Proposed Standard

[Engin Gunduz <]

Dear colleagues,

We'd like to present the view of the RIPE NCC on the discussions
on the RPSLng draft.

Although it is not explicitly discussed in the draft, the
transition issue was thought on.  It was decided to use
mp-* attributes to ease the transition.  That way, the old
clients that use the routing registry that supports RPSLng
can simply ignore the new attributes and new object classes
and continue to work  (this is the expected behaviour of
clients, RFC2622 sections 10.2 and 10.3).

Thus, it is not really necessary to equip the whois server
with the capability of detecting if the client is RPSLng
capable or not.

Perhaps what we need to do is to document these in
the draft.

At any rate, we think it is useful to change the protocol
to allow negotiation of object format, but this is out of
scope of RPSLng effort.  The relevant effort to change
(or, re-design) the protocol is the CRISP effort, please see
http://www.ietf.org/html.charters/crisp-charter.html .

On the subprotocol issue: IPv4 address family has defaulted to 
ipv4.unicast generally (in Cisco IOS software, for instance, 
which is widely used).  Therefore the change of the meaning to 
ipv4.unicast+ipv4.multicast may cause confusion.

We have been trying to come up with a solution so that the
users of whois database can start using it to publish their
IPv6 and multicast policies.  The effort started more than
a year ago and our users are getting more and more impatient
to see a solution.  Actually, long ago they started to
"document" their IPv6 and multicast policies using alternative
methods, please see

so it seems like it's time come up with a solution and implement it.
We think the current draft meets the needs.
