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

A.

LISP (Locator/ID Separation Protocol) is a networking protocol that separates the device identity from its location, making it easier to manage IP addresses and support mobility across networks.

LISP has four main components:

• EID (Endpoint IDentifier): the device identifier
• RLOC (Routing LOCator): the device location
• ITR (Ingress Tunnel Router): the device that receives packets from an endpoint and encapsulates them with a new header to send them to the MR
• ETR (Egress Tunnel Router): the device that receives packets from the MR and decapsulates them to send them to the endpoint
• MR (Mapping Resolver): the device that maps EIDs to RLOCs and vice versa
• MS (Mapping Server): the device that stores and manages the mapping database for a site or domain

To answer the question, the LISP device that is responsible for publishing EID-to-RLOC mappings for a site is the Mapping Server (MS). The MS stores and manages the mapping database for a site or domain, and provides the mappings to the MR when requested.

Therefore, the correct answer is D. MS.
