1.2.4 Configuring P Router

P router does not maintain VPN routes, but do keep connection with public network and
coordinate with PE in creating LSPs. These configurations are required on P router:
Configure MPLS basic capacity and enable LDP on the interfaces connecting P
router to PE router, for forwarding MPLS packets. For details, refer to MPLS
Configuration.
Enable OSPF protocol at the interfaces connecting P router to PE router and
import direct-connect routes.
