Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 537

Which device is responsible for finding EID-to-RLOC mapping when traffic is sent to a LISP-capable site?

Answer options

• A. map resolver
• B. egress tunnel router
• C. map server
• D. ingress tunnel router

Correct answer: D

Explanation

The ingress tunnel router is responsible for determining the EID-to-RLOC mapping when traffic is sent to a LISP-enabled site. The map resolver and map server have different roles in the LISP architecture; the map resolver finds the mapping, while the map server stores it. The egress tunnel router manages traffic leaving the LISP site, not the initial mapping process.
