Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 858

Which LISP component is required for a LISP site to communicate with a non-LISP site?

Answer options

• A. Proxy ITR
• B. ITR
• C. ETR
• D. Proxy ETR

Correct answer: D

Explanation

The correct answer is D, Proxy ETR, as it enables communication between LISP and non-LISP sites by translating LISP packets. Option A, Proxy ITR, is not suitable for this purpose as it deals with incoming traffic for LISP sites, while B, ITR, and C, ETR, do not facilitate interactions with non-LISP sites.
