Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 525

Which tag is used by the PE router to forward the packet to the correct customer?

Answer options

• A. RD
• B. extended-community
• C. RT
• D. VNI

Correct answer: C

Explanation

The correct answer is RT (Route Target), which is specifically used by PE routers to determine the appropriate customer context for forwarding packets. The other options, such as RD (Route Distinguisher) and extended-community, serve different functions in routing and do not directly handle customer packet forwarding. VNI (Virtual Network Identifier) is used in overlay networks and is not related to the customer-specific routing in this context.
