Regarding global BGP community values

Fri Oct 8 11:12:28 UTC 1999

To go forward, I'd like to say here that the new draft are prepared now
concerning the global communities.

But the approach used was quite other. Such recommendations are useful
only if a lot of ISP support it. And I prefer to start from 1 - 2 very
simple, intuitively clean, and safe communities, and (may be) reserver
some community numbers for the future use in the same purposes.

The proposals made here was on the right way, but was a very, very complex
and discussional by the form, and I prefer (from ISP point of view) to
see 2 standard community NOW to having 20 standard communities in the few
future.

Remember - any extra control can violate existing policies, and if some
proposals can't be realized withouth such violation, they have not a
chance to became global ones.

Alex. /hope this short proposals will be published here in a few days/
