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 to utilise L2VPN service provided by the provider. The routing protocol used could be static or dynamic (an interior gateway protocol like OSPF or an exterior gateway protocol like BGP).
The customer edge router can either be owned by the customer or service provider.
