Wouldn't it be better to just change the definition of community in the RPSL dictionary so that a community of <digit>+ ":" <digit>+ ":" <digit>+ is valid and then have the tools either barf if they don't understand or do "the right thing"? That would seem more consistent with the current scheme where a community can either be an integer or <digit>+ ":" <digit>+. I assume a router that can deal with large communities will accept standard ones in the same clauses if someone wants to do that for local use only communities. Mark.
