Ex4600 switch route import using rib-groups but still not able to ping

Iam trying to ping the loopback address of the EX-4600 switch where loopback is the only interface in master routing instance and iam using rib-groups to populate the static route pointing towards my cisco router connected in the uplink. There is a static route configured on the cisco router pointing to the link in the v1-vrf. I see the static default routes and loopbacks(direct) routes on both the routing tables, but iam not able to ping the loopback from my uplink cisco router. If i put the loopback on the v1-vrf, its all working fine.

Here is the configuration on the switch.

unit 0 {
    family inet {
        address 10.10.59.246/32;
    }
}

interface ge-0/0/0
description "Connection to uplink cisco";
vlan-tagging;
unit 0 {
    vlan-id 28;
    family inet {
        address 10.10.59.82/30;
    }
}
unit 1 {
    vlan-id 29;
    family inet {
        address 10.10.59.242/30;
    }
}
