[j-nsp] Match multiple bgp communities in a policy with AND condition

["Rolf Hanßen"]

Hello,

I wanted to match 2 named communities in a policy and I am interested how
you solve such things.

policy-options {
	policy-statement xy {
		from {
			community [a b];
		}
	}
	community a members 123:1;
	community b members 123:2;
}

This matches in case one of the communities is set (typical Juniper OR
condition).

Is there a way to match "one" AND "two"?
I would like to avoid creating a third community with both members set
because in case of many combinations this does not scale well.

Is there maybe even a way to combine both like "a and (b or c)"?

Kind regards
Rolf
