Re: [Idr] draft-dong-idr-node-target-ext-comm-05.txt - WG Adoption and IPR call (9/27 to 10/11/2022)

Hi Tom,

> Is the term ASBR well-understood in the context of BGP

It is a very well known term and widely used across many documents in the
context of BGP protocol. Sometimes you will see folks abbreviating it to
"BR", but the BGP speaker which talks EBGP is almost always
called Autonomous System Border Router (I used word "almost" as there is an
exception - confederations).

Thx,
Robert.
