[j-nsp] Merging routes from VRF to inet.0

[Dave Bell]

rib-groups is indeed the simplest way to do this. Something like this
should work for you:

routing-options {
    rib-groups {
        import_inet0 {
            import-rib inet.0;
            import-policy my_pol;
        }
}

policy-options {
    policy-statement my_pol {
        term 10 {
            from {
                route-filter a.b.c.d/32 exact;
            }
            then accept;
        }
        term 30 {
            then reject;
        }
    }
}
routing-instances {
    my_instance {
        routing-options {
            static {
                route 0.0.0.0/0 next-table inet.0;
            }
            auto-export {
                family inet {
                    unicast {
                        rib-group import_inet0;
                    }
                }
        }
    }
}
