Chapter 12. Layer 2 and Layer 3 VPNs > Configuring Layer 3 VPN Tunnel Interface...

Configuring Layer 3 VPN Tunnel Interfaces

To configure a Layer 3 VPN as the tunnel end point of a generic routing encapsulation (GRE) tunnel interface, you need to specify which routing table to search on the router, indicated by the destination IP address, so that the appropriate routing table can be searched for the routing prefix, because identical routing prefixes can appear in different routing tables. To configure a Layer 3 VPN as the tunnel end point of a tunnel interface, include the routing-instance statement:

[edit interfaces interface-name unit unit-number tunnel {
routing-instance {
  destination routing-instance-name;
}
