How does one distinguish "informational" and "action" of unknown communities?
"if the community is unknown why would you take any action except to strip it?"
the action ones are divisible by 3 </sarcasm> you are in a twisty maze where there are no formnally defined semantics, only a #:# syntax. if there were general formal semantics, it could have been put directly in bgp attributes.
isn't it really that the communities (well known aside) mean what you want them to mean? you get to be creative and have fun!! imagine the fun you'll leave behind with your follow on networking folks at your job!! great times!
