Which device is responsible for finding EID-to-RLOC mapping when traffic is sent to a LISP-capable site?
The device responsible for finding EID-to-RLOC mapping when traffic is sent to a LISP-capable site is the ingress tunnel router (ITR). The ITR is tasked with locating the appropriate RLOC for a given EID by querying the LISP mapping system. Once the EID-to-RLOC mapping is found and cached, the ITR encapsulates the outgoing packets with the correct RLOC destination.
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 and one of the RLOCs from the mapping cache entry as the IP destination. The ITR then routes the packet normally.
Passed My Exam on 15th , 100% From here, Three Labs GLBP, BGP R1 R3, Netflow IP Sla.
I thought Labs GLBP, Netflow IP Sla were absolute,
Congratulations @nobodyknows11
Answer is D https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_lisp/configuration/15-mt/irl-15-mt-book/irl-overview.pdf Thank god for discussions or I will fail lol
another broken question, one word changes question's whole meaning.
Responsible means to search for RLOC and route the traffic in time. So D.

D - read the working of the question.

D is correct
...........................
D is correct
An ETR connects a site to the LISP-capable part of a core network (such as the Internet), publishes EID-to-RLOC mappings for the site, responds to Map-Request messages, and decapsulates and delivers LISP-encapsulated user data to end systems at the site
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 Answer is ETR keyword"publish"
Publish means ; ETR Finding means: ITR
I assume you mean the answer is ITR due to "finding" and the line above is just a typo.
Map server: This is a network device that learns EID-to-prefix mapping entries from an ETR and stores them in a local EID-to-RLOC mapping database. I think C is correct
D is the correct my bad. I totally misunderstood this.
I think the answer is D. An ITR is responsible for finding EID-to-RLOC mappings for all traffic destined for LISP-capable sites
Agree D, https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_lisp/configuration/15-sy/irl-15-sy-book/irl-overview.pdf
