Configuring an IGP on the PE and P Routers

For Layer 2 VPNs, Layer 3 VPNs, virtual-router routing instances, and VPLS to function properly, the service provider’s PE and P routers must be able to exchange routing information. To allow them to do this, you must configure either an IGP or static routes on these routers. You configure the IGP on the master instance of the routing protocol process at the [edit protocols] hierarchy level, not within the routing instance used for the VPN—that is, not at the [edit routing-instances] hierarchy level.

When you configure the PE router, do not configure any summarization of the PE router’s loopback addresses at the area boundary. Each PE router’s loopback address should appear as a separate route.

For information about configuring IGPs and static routes, see the Junos Routing Protocols Configuration Guide.
