Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 831

Which device, in a LISP routing architecture, receives and de-encapsulates LISP traffic for endpoints within a LISP-capable site?

Answer options

• A. MR
• B. ETR
• C. MS
• D. ITR

Correct answer: B

Explanation

The correct answer is B, ETR (Encapsulating Tunnel Router), which is designed to receive and de-encapsulate LISP traffic for endpoints within a LISP-enabled site. The other options, MR (Mapping Resolver), MS (Mapping Server), and ITR (Ingress Tunnel Router), serve different roles in the LISP architecture, such as resolving mappings or encapsulating traffic, but do not perform the specific function of de-encapsulation for local endpoints.
