IGP Shortcuts and VPN Environments

IGP shortcuts (configured under the protocols mpls traffic-engineering bgp-igp hierarchy level and under the protocols ospf traffic-engineering shortcuts hierarchy level) do not work in VPN environments. IGP shortcuts move routes in the inet.3 routing table to the inet.0 routing table. VPN IBGP (which belongs to family inet-vpn) relies on next hops that are in the inet.3 table, so IGP shortcuts are incompatible with VPNs.
