I have been selected to do a routing directorate “early” review of this draft.

The routing directorate will, on request from the working group chair, perform
an “early” review of a draft before it is submitted for publication to the
IESG. The early review can be performed at any time during the draft’s lifetime
as a working group document. The purpose of the early review depends on the
stage that the document has reached.

For more information about the Routing Directorate, please see

Document: draft-ietf-bess-bgp-multicast-05.txt
Reviewer: Ben Niven-Jenkins
Review Date: 10 November 2023
Intended Status: Standards Track

Summary: This document is basically ready for publication, but has nits that
should be considered prior to being submitted to the IESG.

Comments: The document is well written and easy to read and understand.


Section 1.2.4 - “For unlabeled (x,g) unidirectional trees, the upstream peer
MAY prefer LAN interfaces to send traffic, since multiple downstream peers may
be reached simultaneously, or it may make a decision based on local policy,
e.g., for load balancing purpose.”

I do not understand why the first MAY is capitalised. Is this a mistake and it
should be in lowercase like the other instances of may in that sentence?

Section 1.2.5 - “PIM and BGP MUST not be used simultaneously between two
neighbors for multicast purpose, and routers connected to the same LAN MUST be
transitioned during the same maintenance window.”

I think the “MUST not” should be “MUST NOT”?
