Which statement about LISP encapsulation in an EIGRP OTP implementation is true?

Question

Options

• AOTP uses LISP encapsulation for dynamic multipoint tunneling.
• BOTP maintains the LISP control plane.
• COTP uses LISP encapsulation to obtain routes from neighbors.
• DLISP learns the next hop.

• A
  88% (29)
• B
  3% (1)
• C
  3% (1)
• D
  6% (2)

Explanation

EIGRP OTP and LISP Encapsulation

Why A is Correct: EIGRP Over the Top (OTP) leverages LISP (Locator/ID Separation Protocol) encapsulation specifically to create dynamic multipoint tunnels between EIGRP sites across an underlying IP network (such as the internet or an MPLS core), allowing routers to form EIGRP neighbor relationships without pre-configured static tunnels.

Why the Distractors are Wrong:

• B is wrong because OTP does not maintain the LISP control plane - OTP uses only LISP's data plane encapsulation mechanism, not its full control plane architecture.
• C is wrong because routes are learned through the EIGRP protocol itself (via EIGRP updates between neighbors), not through LISP encapsulation.
• D is wrong because EIGRP determines the next hop through its own routing process; LISP simply provides the tunneling/encapsulation mechanism to transport the traffic.

Memory Tip: Think of OTP as "EIGRP borrowing LISP's jacket (encapsulation) to travel across foreign networks dynamically" - EIGRP still does all the routing work, it just wears LISP to get there. The keyword pairing to remember is OTP = Dynamic Multipoint + LISP encapsulation.
