A provider edge router ( PE router) is a router between one network service provider's area and areas administered by other network providers. [ 1] A network provider is usually an Internet service provider as well (or only that). The term PE router covers equipment capable of a broad range of routing protocols, notably: PE routers do not need ...
In the specific context of an MPLS-based virtual private network (VPN), LERs that function as ingress or egress routers to the VPN are often called provider edge (PE) routers. Devices that function only as transit routers are similarly called provider (P) routers. [14] The job of a P router is significantly easier than that of a PE router.
The customer edge router (CE) generally refers to the router at the customer premises that is interconnected with the provider edge router of a service provider's IP/MPLS network. [1] The CE router may peer with the provider edge router (PE) and exchanges routes with the corresponding VRF inside the PE for L3VPN services, or it may be connected ...
In telecommunications, a customer-premises equipment or customer-provided equipment ( CPE) is any terminal and associated equipment located at a subscriber's premises and connected with a carrier's telecommunication circuit at the demarcation point ("demarc"). The demarc is a point established in a building or complex to separate customer ...

A cable modem termination system ( CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers. A CMTS provides many of the same functions provided by the DSLAM in a DSL system.
At the edge of an MPLS provider's network, a router which connects to a customer's network is called a Provider Edge (PE) router. Similarly, the customer's edge router at the other end of the connection is called a Customer Edge (CE) router. Within an MPLS network, a PE router needs to be configured to associate each route distinguisher with ...
