DRAG DROP
Drag and Drop the key components of LISP from left onto the correct definitions on the right

Answer:

Explanation: Ingress tunnel router – it receives packets from site-facing interfaces (internal hosts) and either
LI SP encapsulates packets to remote LISP sites or the ITR natively forwards packets to non LISPsites. Egress tunnel router – It receives packets from core-facing interfaces (the internet) and either decapsulates LISP packets or delivers them to local EIDs at the site Map server – it receives map- register control packets from ETRs.
Map resolver – it receives map-requests encapsulated to it from ITRs.
Routing locators – It is assigned to devices that makeup the global routing system. Endpoint identifiers --- it is assigned to end hosts.
Note: Looks correct, just double check cisco definitions of Ingress/Egress Tunnel routers.
