[nsp] BGP additive communities

Hi!

Can someone please point me to a link on a case study of using community attribute
for a large ISP/IXP? Real life examples, aside from RFC1997and RFC1998.

What is the limit of community attribute when I tag my routes with the "additive" keyword?

something like:

mix_route-server>sh ip bgp 202.78.64.0

  9670 6648
    203.167.95.20 from 203.167.95.20 (203.167.95.20)
      Origin IGP, metric 100, localpref 100, valid, external, ref 2
      Community: 9670:6648 9670:1001

which shows I have the route with two "colors" and policies applied.

TIA
