Communities (except the standardized well known ones) are extremely
diverse. For those that support even more granular traffic engineering
by limiting which of their peers your routes might be transiting, I
believe there are 2 distinct methods of using communities.
The nature of communities, and the different levels of support and
traffic engineering capabilities makes it difficult for it to be
standardized. It would take even longer for anyone to adopt such a
standard due to the sheer volume of routers and customers who would have
to adapt from long term established policies.
