Question

Quizplus · Accepted Answer

BGP (Border Gateway Protocol) is a path vector protocol that sends updates between routers using TCP. It is used to exchange routing information among different autonomous systems on the internet. IS-IS and OSPF are both link-state routing protocols, and RIP (Routing Information Protocol) is a distance-vector routing protocol, none of which use TCP for updates between routers. Therefore, the best choice is D, BGP.
