Couldn't you express this with the interas-in attribute?
Say that the following addresses<->router mappsings are valid.
NAP
----
NAP1 AS1 192.141.10.1
NAP1 AS2 192.141.10.2
NAP2 AS1 192.142.10.1
NAP2 AS2 192.142.10.2
NAP3 AS1 192.143.10.1
NAP3 AS2 192.143.10.2
Then wouldn't the policy be...
aut-num: AS1
interas-in: from AS2 192.141.10.1 192.141.10.2 accept <metric> AS2
interas-in: from AS2 192.142.10.1 192.142.10.2 accept <metric> AS2
interas-in: from AS2 192.143.10.1 192.143.10.2 accept <metric> AS2 AND {10/8}
