Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 509

Which router attaches the VPN label to incoming packets from CE routing?

Answer options

• A. P router
• B. PE router
• C. CE router
• D. core router

Correct answer: B

Explanation

The PE router is the correct answer as it is specifically designed to handle VPN services and add the necessary labels to incoming packets from CE routers. The P router primarily manages the transport of labeled packets but does not add VPN labels, while the CE router is the customer edge device that does not manage labels. Core routers typically route packets within the backbone of the network without VPN functions.
