Q

What it the purpose of the LISP routing and addressing architecture?

A. It creates two entries for each network node, one for its identity and another for its location on the network.

B. It allows LISP to be applied as a network virtualization overlay though encapsulation.

C. It allows multiple instances of a routing table to co-exist within the same router.

D. It creates head-end replication used to deliver broadcast and multicast frames to the entire network.

A

A. It creates two entries for each network node, one for its identity and another for its location on the network.
