[j-nsp] as-path filtering

[Samit]

Thanks Scott/Tarique, changed the rule as per your advice but for some
reason it is not working...and could not figure out either.

protocols {
     bgp {
         group "ebgp-test" {
             type external;
             import test-in;
             peer-as 200;
             neighbor 192.168.0.1
             }
         }

policy-options {
     policy-statement test-in {
             from as-path [a b];
             then reject;
         }
         as-path a "_1234$";
         as-path b "_5678$";
     }
}


Still seeing routes originated from AS1234 and 5678 in the routing table.

Regards,
Samit
