Understanding the Purpose of LISP Routing and Addressing Architecture

A.

The Locator/ID Separation Protocol (LISP) is a routing and addressing architecture that separates the identity of a network device from its location on the network. The purpose of LISP is to provide a more scalable and flexible way of routing traffic across the internet.

Option A is incorrect. LISP does not create two entries for each network node; rather, it separates the identity of the node from its location on the network.

Option B is correct. LISP allows for network virtualization overlays by encapsulating packets with an additional header that includes location information. This allows for more efficient routing across the internet.

Option C is incorrect. LISP does not allow for multiple instances of a routing table to co-exist within the same router.

Option D is incorrect. LISP does not create head-end replication for broadcast and multicast frames.

In summary, the purpose of the LISP routing and addressing architecture is to provide a more scalable and flexible way of routing traffic across the internet by separating the identity of a network device from its location on the network, and by allowing for network virtualization overlays through encapsulation.
