Configure an IGP on the PE Routers

To allow PE routers to exchange routing information, 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 Layer 2 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 routing protocols and static routes, see the JUNOS Internet Software Configuration Guide: Routing and Routing Protocols.
