Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 390

Which Cisco Locator/ID Separation Protocol (LISP) device receives packets from remote site facing devices and either decapsulates the LISP packets or routes them natively?

Answer options

• A. ITR
• B. ETR
• C. MS
• D. MR

Correct answer: B

Explanation

The correct answer is B, ETR, which stands for Egress Tunnel Router. It is responsible for decapsulating LISP packets or routing them natively. The other options are incorrect as ITR (A) is for ingress processing, MS (C) is the mapping system, and MR (D) is a multi-cast router, none of which handle packets from remote sites in the manner described.
