Router R1 is configured using VRF’s to support customer VPN’s. Some customers are using the same private IP address space. Which of the following is used to ensure that these routes are unique when advertised throughout the VPN?
When routers are configured with Virtual Routing and Forwarding (VRF) to support customer VPNs, different customers can use the same private IP address spaces. A Route Distinguisher (RD) is used in such scenarios to ensure that these routes are unique when advertised throughout the VPN. The Route Distinguisher adds a unique identifier to the IP address, effectively making the routes globally unique and preventing overlap.
