MPLS Label Edge Router
A Label Edge Router (LER) is a router found within an MPLS environment. It is also known as a PE router or a Provider Edge router. Refer to the following MPLS topology.
The PE routers are the devices found at the edge of the MPLS network and connect directly to the Customer Edge or CE routers. The PE becomes a routing peer with the CE using a routing protocol such as OSPF, EIGRP, or BGP, but static routing can also be used. The PE router also connects directly with a P router.
