Summary:
The draft updates the BGP Monitoring Protocol BMP by adding access to the
Adj-RIB-Out RIBs. There are some unclear areas that need authors to clarify.
Major issues:
Minor issues:
Section 1 last paragraph:
It is not clear if BMP sender send to multiple BMP receivers or just to
one
"BMP receiver". The first part of the sentence says "..send to a BMP
receivers", the second part says ".. advertise to BGP peers, .."
Suggest to make it consistent, such as sending to multiple, or just one.
"..
to send to BMP receivers what it advertises.."
[tievens] There are one or more receivers for each sender. The implementation
defines how many receivers it can send to. I've updated it to:
"Adding Adj-RIB-Out provides the ability for a BMP sender to send to
BMP receivers what it advertises to BGP peers, which can be used for
outbound policy validation and to monitor RIBs that were advertised."
[Linda] Yes, your new text is much more clear.
Does a BMP sender also send out Adj-RIB-In? it is not clear to.
[tievens] Yes, RFC7854 defines Adj-RIB-In only. How about the below?
"BGP Monitoring Protocol (BMP) RFC 7854 [RFC7854] only defines Adj-
RIB-In being sent to BMP receivers. This document updates section
4.2 [RFC7854] per-peer header by adding a new flag to distinguish
Adj-RIB-In verses Adj-RIB-Out. BMP senders use the new flag to send
either Adj-RIB-In or Adj-RIB-Out."
[Linda] Thank you for the change. It is very clear now (sorry that I didn't
devote time to read the RFC7854).
Section 6 first sentence: just curious which BMP messages are NOT
applicable to
Adj-RIB-In or Adj-RIB-out? If it is specified in other documents, please
add
a reference.
[tievens] How about the below update to clarify some. I didn’t want to create
a list
of them because it could be different in updated/new drafts.
"Many BMP messages have a per-peer header but some are not applicable
to Adj-RIB-In or Adj-RIB-Out monitoring, such as peer up and down
notficiations."
[Linda] thanks. It is very clear now.
Nits/editorial comments:
Thank you.
