What is TRUE about a CE router that is involved in a VPN service?

A CE (Customer Edge) router is integral to a VPN service as it acts as the entry point for customer traffic into the service provider's network. It is typically positioned at the customer’s site and is responsible for forwarding packets to the connected PE (Provider Edge) routers.

The statement regarding the connection between the CE router and the PE router emphasizes the functionality and operational role of the CE router within a VPN setup. CE routers do not directly engage with multiple CE routers for their functioning; instead, they are configured to interact primarily with PE routers to manage the flow of data packets between the customer’s internal network and the VPN service provided by the service provider.

This relationship is fundamental to how VPNs operate, allowing CE routers to leverage the service provider's infrastructure to ensure that traffic is appropriately routed, encapsulated, and managed securely across potentially shared networks.

In contrast, the other options do not accurately reflect the characteristics and roles of a CE router. It is not aware of the VPN services because that level of awareness falls within the PE routers. A CE router does not reside on the service provider's premises; rather, it is located at the customer’s site. The connection specifics regarding other CE routers are misaligned with the primary function of the CE
