I am the assigned Gen-ART reviewer for the dvmrp informational I-Ds..
For background on Gen-ART, please see the FAQ at
<http://www.alvestrand.no/ietf/gen/art/gen-art-FAQ.html>.
Please wait for direction from your AD before posting a new version
of the draft.
These documents appear ready for publication as Informational RFCs.
The following minor comments should be considered if there is other
reason to revise the document.
Protocol:
In section 2.4 on Designated Forwarder, in the event of a metric
tie, the rotuer with the lowest IP address is the designated
forwarder. I believe that this is the router whose interface to the
mutli-access network has the lowest IP address. (Not, for example,
the lowest loopback address, etc.) A few extra words here would be a
good idea.
Section 2.5.1 talks about learning local group membership from
IGMP. Shouldn't there be some mention of source specific membership
here? (Or am I confused and that has gone away?)
I am guessing that the 3 octet network mask technique is used
here for backwards compatibility, even though a network prefix length
would be shorter? (The protocol goes to significant lengths to save
bytes, and the text does not say why that is not used.)
Section 3.4.5 introduces the term "flash update." While I have
seen this in implementations, it is not a widely used term in our
specifications. An explanation would be a good idea.
Applicability Statement:
It would have been nice to see a clearer statement of why one
would use this rather than either PIM-DM or M-OSPF. (There is
probably more, but one piece of the answer is the support for tunnels
in DVMRP.)
Given that restarting routers can, via the generation ID, cause
significant amounts of graft, graft-ack, and prune messages, should
this applicability statement say something about assuming underlying
stability of the network?
