Which routers are MPLS VPNs aware of?

P routers
all provider routers
CE routers
PE routers

Explanation: In the MPLS L3 VPN architecture, PE routers are the only routers that see all routing aspects of the VPN. They exchange VPN routes with CE routers, maintain separate VRF tables for customer isolation, and exchange VPNv4/VPNv6 routes with other PE routers via MP-BGP. In contrast, P routers remain unaware of VPN routes and only perform label switching based on core reachability.
