    Hi there, 

    Does the following config filter out bgp prefixes from the primary-table inet.0 as well as from the secondary table test.inet.0 ? My understanding is that the RIB-GROUP import-policy does not process prefixes destined for the primary-table but only for the secondary-table(s).

     

       rib-groups {

            TEST-RIB-GROUP {

                import-rib [ inet.0 test.inet.0];

                import-policy FILTER;

            }

        }

    policy-options {

        policy-statement FILTER {

            term FILTER-TERM {

                from protocol bgp;

                then reject;

            }

     Thanks a lot guys

    Your understanding is correct. There's no way that rib-group import policy can change the route for primary RIB. 

    This is applied between primary RIB and seconary RIB, only affect routes being put into secondary RIB
