Configuring a VPN Tunnel for VRF Table Lookup
You can configure a VPN tunnel to facilitate VRF table lookup based on MPLS labels. You might want to enable this functionality to forward traffic on a PE-router-to-CE-device interface in a shared medium, where the CE device is a Layer 2 switch without IP capabilities (for example, a metro Ethernet switch), or to perform egress filtering at the egress PE router.
For more information about VPN tunnels and VT interfaces, see the Junos Services Interfaces Configuration Release 12.3.
