The problem with communities here is that: * bgp communities apply to a route announcement, not an arbitrary network. The /16 is being announced here and passing through above.net, and if above.net wanted to tag the specific host they'd have to announce the /32. * besides the few well-known ones, each router participating needs to know what the community maps to. So unless I've missed something here, you can't use BGP communities. Adrian -- Adrian Chadd "Sex Change: a simple job of outside <[email protected]> to inside plumbing." - Some random movie
