Which solution supports the use of overlapping addresses on a PE router?
- MPLS
- VRF
- MP-BGP
- IPsec VPNs
Explanation: In an MPLS L3 VPN architecture, Virtual Routing and Forwarding (VRF) tables allow a Provider Edge (PE) router to maintain multiple independent routing tables. This isolation ensures that different customers can use overlapping or identical private IP address spaces without conflict, as each VRF carries its own unique Routing Information Base (RIB) and Forwarding Information Base (FIB).
