[nsp] BGP community issue or provider issue?

[Arie Vayner]

Hi

You are right, there is no need in a match line. Ignoring it just executes 
the set commands on everything.
What you are doing is perfectly correct, assuming the community has any 
meaning to the provider.

What does the filter list filter? Maybe this is the problem?

you can ask a 'show ip bgp <prefix>' from the provider, and look for the 
community, or use a route-server in their AS
