Which action is a LISP ITR responsible for?
A LISP Ingress Tunnel Router (ITR) is responsible for finding EID-to-RLOC mappings. When dealing with traffic destined for LISP-capable sites, the ITR looks up the EID-to-RLOC mapping to determine the appropriate RLOC (Routed Locator) to forward the packet. This involves querying the mapping system to obtain the correct mapping, allowing the ITR to encapsulate and forward the packet appropriately.
Given answer is correct. LISP Ingress Tunnel Router (ITR) An ITR is responsible for finding EID-to-RLOC mappings for all traffic destined for LISP-capable sites. When the ITR receives a packet destined for an EID, it first looks for the EID in its mapping cache. If the ITR finds a match, it encapsulates the packet inside a LISP header with one of its RLOCs as the IP source address https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_lisp/configuration/15-mt/irl-15-mt-book/irl-overview.pdf
The Ingress Tunnel Router (ITR) is responsible for sending map requests and processing received map replies to resolve EID-to-RLOC mappings. Additionally, on the data plane side, the ITR encapsulates packets for transmission to remote LISP sites or natively forwards packets to non-LISP sites.
A. Map Resolver receives the Map Request messages and forwards them to the ETR. The ETR replies to them B. Basically all routers do this. C. ITR D. There is no such LISP message as a "registration request". The message is called "Map Register" message, it is sent by the ETR and processed by the Map Server
