[c-nsp] bgp communities over vpn mpls

[Keegan Holley]

My company has a small network of a few thousand customers and some internal stuff.  We also buy VPN services from a large tier 1 provider.  I can tell you from experience that the guidelines depend on your carrier and what business relationship you have with them.  (read $$$)

It's easier to remove all customer communities at the edge so some providers probably do that as.  Others may allow specific values for specific reasons the same way internet providers will allow customers to prepend and increase local-pref by sending communities.  The best thing is to consult your specific provider.
