Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 43

Which LISP device is responsible for publishing EID-to-RLOC mappings for a site?

Answer options

• A. ETR
• B. MR
• C. ITR
• D. MS

Correct answer: A

Explanation

The ETR (Egress Tunnel Router) is responsible for publishing EID-to-RLOC mappings, as it manages the mapping database required for the translation. In contrast, the MR (Mapping Resolver) is used for resolving mappings, the ITR (Ingress Tunnel Router) is for encapsulating packets, and the MS (Mapping Server) is for storing mappings but not for publishing them.
