https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_lisp/configuration/xe-3s/irl-xe-3s-book/irl-overview.htmlLISP (Locator/ID Separation Protocol) is a network architecture and protocol that separates the device identity (ID) from its location (locator) to allow for more efficient routing and mobility management. LISP uses several namespaces to accomplish this separation, including the Endpoint ID (EID) namespace and the Routing Locator (RLOC) namespace.
Therefore, the correct answers to this question are B. RLOC and E. EID.
Explanation of the namespaces:
- Endpoint ID (EID): It is a namespace used by LISP to identify devices or hosts. It is assigned by the enterprise administrator and is typically a globally unique IP address assigned to a device or host.
- Routing Locator (RLOC): It is a namespace used by LISP to identify the location of a device or host in the network. It is typically an IP address assigned to a device's interface, and it is used by routers to forward traffic to the appropriate destination.
The other options are not namespaces used by LISP:
- TLOC: This option is not a namespace used by LISP.
- DNS: Domain Name System is not a namespace used by LISP.
- VTEP: VXLAN Tunnel Endpoint is not a namespace used by LISP. It is used in overlay networks for network virtualization.
