Note: This ballot was opened for revision 08 and is now closed.
Summary: Has enough positions to pass.
The title talks about "LISP for multicast environments" but the Abstract
is specific to "inter-domain multicast routing". Should the document
title be updated accordingly or is the Abstract wrong?
It is possible that the confusion is at bullet 2 of Section 2 where it
is implied that a "domain" is a LISP site such that "inter-domain" means
between LISP sites. It would be helpful not to re-use "domain" in ths
way (we are used to it meaning inter-AS and inter-area).
Since multicast between LISP sites is just a special case of multicast
using LISP, you could stike the text from the Abstract.
- It'd be good to know if this use of LISP claims some benefit
over "ordinary" multicast, or if you're just making multicast
work ok in a LISP environment. It doesn't matter much, but it'd
be nice to say so the reader knows whether or not to get excited:-)
- The intro leaves me wondering if a multicast group address is regarded
as an EID or RLOC, or if it varies or if it matters. Just wondering.
That is described at the start of section 5, but earlier would be good
- You may want to expand the RPF acronym.
- p5, 1st para after bullets - the 1st sentence talks about "protocols"
but the 2nd talks about "the protocol" - seems wrong.
- Section 10, 1st para, last sentence is missing something, maybe
s/need to/and need to/?
"By using the traffic engineering features of LISP" needs a ref.
The subtleties of different m/c paths surely belongs after the basic
description rather than as the first item
The protocols in section 7 need references
Mpriority seems to lack a definition
draft-ietf-lisp-ms contains a section entitled "Open Issues and
Considerations", which provides a good start toward understanding the
parameters of the experiment we're engaging in here, and perhaps some
dimensions for measuring success. It would be helpful for this document to
contain a similar section.
The terminology section repeats definitions from the base LISP spec. This seems
like a bad idea. It would be better to reference those definitions and here
simply provide the extended information that applies only to multicast
The Security Considerations section seems rather sparse. Does the use of LISP
in a multicast environment truly have no security implications whatsoever?
In the numbered list of scenarios in section 9.1, there are a couple
of occurrences of the term "LISP sites." Should "LISP sites" be
replaced by "LISP-Multicast sites"?
Is it assumed that a uLISP site uses non-LISP transport for multicast?
If so, it would be helpful for the document to state that situation
In the Security Considerations section, if this document introduces
no additional security concerns beyond those in LISP base spec,
that assertion should be made explicitly.
