Question 4

What is the function of a LISP PITR?

AIt encapsulates IP packets from non-LISP sites with a LISP header.

BIt accepts registration requests and aggregates successfully registered EID prefixes to client ITRs.

CIt is responsible for publishing the site EID-to-RLOC mappings.

DIt forwards encapsulated messages to the MS to the authoritative ITR for the EID.

Answer : A

The correct answer is A. It encapsulates IP packets from non-LISP sites with a LISP header.

In Cisco LISP, a PITR (Proxy Ingress Tunnel Router) provides connectivity between non-LISP sites and LISP sites. Cisco documentation states that a PITR performs ITR mapping database lookups and LISP encapsulation functions on behalf of non-LISP-capable sites. Cisco also explains that the PITR attracts traffic from non-LISP sites that is destined for LISP EID space, then encapsulates and forwards that traffic to LISP sites.

That is exactly what option A describes.

Why A is correct:

A PITR acts like an ingress tunnel router for non-LISP sources. When traffic comes from a non-LISP site toward a LISP destination, the PITR:

receives the traffic,

performs the mapping lookup,

adds the LISP header,

and forwards the encapsulated packet toward the correct LISP site.

Why the other options are incorrect:

B . It accepts registration requests and aggregates successfully registered EID prefixes to client ITRs.

This describes the role of a Map Server (MS), not a PITR. Cisco states that the MS receives registrations from ETRs and advertises aggregates for registered EID prefixes into the mapping system.

C . It is responsible for publishing the site EID-to-RLOC mappings.

This is also associated with the Map Server / mapping system, not the PITR. The PITR uses mappings for encapsulation; it does not publish them.

D . It forwards encapsulated messages to the MS to the authoritative ITR for the EID.

This is incorrect terminology and mismatched function. Cisco explains that a Map Resolver (MR) accepts encapsulated Map-Request messages from ITRs and forwards them toward the appropriate Map Server or authoritative ETR, not an authoritative ITR.

ENCOR exam point:

Remember these LISP roles clearly:

ITR = encapsulates traffic toward LISP sites

ETR = decapsulates traffic arriving at LISP sites

PITR = performs ITR function for non-LISP to LISP traffic

MS/MR = mapping-system control-plane components
