Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 470

Which Layer 3 VPN attribute installs customer routes in the VRF?

Answer options

• A. RD
• B. RT
• C. extended-community
• D. MPLS label

Correct answer: B

Explanation

The correct answer is B, RT (Route Target), which is used to identify which routes are imported into or exported from a VRF. RD (Option A) is responsible for route distinguishers, extended-community (Option C) is a type of BGP attribute, and MPLS label (Option D) is used for forwarding packets, but none of these directly install customer routes into the VRF.
