virtual-router routing issue

we want to route the 10.100.101.0/24 to 10.0.8.18 but it does not show up on the route table

root@mx80-core# show routing-instances r1
instance-type virtual-router;
interface lt-0/0/0.0;
interface lt-0/0/0.2;
routing-options {
    static {
        route 10.100.101.0/24 next-hop 10.0.8.18;
    }
}
