VRF route leaking problem

I have added a default route on the main routing table of our PE router, which is redistributed by OSPF in the MPLS core.

The default route is via the VRF interface which was specified using “/ip route add dst-address=0.0.0.0/0 gateway=10.0.1.1%ether1”.

Although the PE has full reach ability, the other routers receiving the default route does not, and when running pings, I get “TTL exceeded” errors…
