MPLS BGP VPN’s not supported accross un-numbered interfaces

MPLS BGP VPN’s not supported across un-numbered interfaces.

When using an un-numbered interface between PE and P routers instead of IP numbered interfaces, the ERX no longer displays VPN routes and shows the next hop address and unreachable even though ICMP Pings to the next hop address are successful.

Platform: Juniper E-Series

SOLUTION:
MPLS BGP VPN’s are not supported on un-numbered interfaces. Assigning an IP address to the interface will allow MPLS Tunnels to be built, and display VPN routes correctly.
