Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 678

Which action is a LISP ITR responsible for?

Answer options

• A. responding to map-request messages
• B. forwarding user data traffic
• C. finding EID-to-RLOC mappings
• D. accepting registration requests from ETRs

Correct answer: C

Explanation

The correct answer is C because the LISP Ingress Tunnel Router (ITR) is tasked with finding EID-to-RLOC mappings to properly route packets. Options A and D involve responding to requests and registrations, which are not the primary functions of an ITR, while option B pertains to forwarding traffic rather than mapping addresses.
