IGP Shortcuts and VPN Environments

IGP shortcuts (configured under the [edit protocols mpls traffic-engineering bgp-igp] hierarchy level and under the [edit 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. Virtual private network (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.
