A Provider Edge router (PE router) is a router between one network service provider's area and areas administered by other network providers. A network provider is usually an Internet Service Provider as well (or only that).
PE routers do not need to be aware of what kind of traffic is coming from the provider's network, as opposed to a P Router that functions as a transit within the service provider's network. However, some PE routers also do labelling.
