Explanation

LISP Network Architecture: Two Namespaces

LISP (Locator/ID Separation Protocol) is built around the fundamental concept of separating two distinct namespaces: EID (Endpoint Identifier), which identifies who a device is (analogous to a name), and RLOC (Routing Locator), which identifies where a device is located in the network topology (analogous to an address). This separation allows for more scalable routing by decoupling device identity from its location, solving the mobility and multihoming challenges in traditional IP networking.

The distractors are wrong for the following reasons:

• TLOC (Transport Locator) is a concept used in Cisco SD-WAN (Viptela), not LISP
• DNS (Domain Name System) is a separate naming system unrelated to LISP's namespace architecture
• VTEP (Virtual Tunnel Endpoint) belongs to VXLAN overlay networking, not LISP

Memory Tip: Think of LISP like a phone book - your name is your EID (who you are), and your phone number/address is your RLOC (where to reach you). The phrase "LISP REally works" can help you remember RLOC and EID as the two key namespaces.
