If you don't speak hex.
What would they be in the new community format? I speak decimal and
hex.

All communities are known by a numerical value. This includes some of
the
"well-known" communities.
Here's an excerpt from RFC 1997:
The following communities have global significance and their
operations shall be implemented in any community-attribute-aware BGP
speaker.
NO_EXPORT (0xFFFFFF01)
All routes received carrying a communities attribute
containing this value MUST NOT be advertised outside a BGP
confederation boundary (a stand-alone autonomous system that
is not part of a confederation should be considered a
confederation itself).
NO_ADVERTISE (0xFFFFFF02)
All routes received carrying a communities attribute
containing this value MUST NOT be advertised to other BGP
peers.
NO_EXPORT_SUBCONFED (0xFFFFFF03)
All routes received carrying a communities attribute
containing this value MUST NOT be advertised to external BGP
peers (this includes peers in other members autonomous
systems inside a BGP confederation).

Subject: BGP Community-lists
Hi all,
I wanted to do a match (in a route-map) for routes with a well known
community attribute, say, for example, no-export. When I did a match
community ? I found that community-list numbers were the only option
availble. My question is, if possible, how would I do a match for a
well
known community attribute?
Thanks in advance, PM
