MPLS VPN Architecture Overview:

MPLS (Multiprotocol Label Switching) VPN is a widely used technology for creating virtual private networks over a shared infrastructure. It involves specific roles for devices in the network.

Explanation of Each Role:

PE (Provider Edge):These devices sit at the edge of the service provider's network and connect to customer sites. They are responsible for assigning labels and managing VPN routes.

P (Provider):These devices are located in the core of the service provider's network.They perform label switching but do not participate in VPN-specific functions.

CE (Customer Edge):These devices belong to the customer and connect to the PE devices. They are unaware of the MPLS network and simply forward traffic to the P

E.  

Aggregation and Core:These terms are not specific to MPLS VPN architecture. "Aggregation" refers to a general networking concept, and "Core" is too broad to describe a specific role in MPLS VPNs.

Conclusion:The correct roles in MPLS VPN architecture are PE, P, and C
