Which of the following is not a function of the routing protocol?
The function that is not a part of the routing protocol is "Discover the physical address of the next hop".
Routing Protocol
When two computers that are not directly connected need to communicate through several networks, a router is usually required. Routers provide a way to open paths through a mesh. Several paths that exist in the Los Angeles and New York offices are marked in Figure R-9. This mesh network provides redundant paths to adjust traffic load or backlinks, often with one path preferred over others for reasons such as cost, speed, or avoiding congestion. The job of a routing protocol is to provide routers with the mutually shared routing information they need to establish the best path through the mesh network.
Overview
(Routing protocol)
When a computer sends a packet, each layer of the network protocol stack on the network All add some information to it. This information can be read by the peer layer protocol on the receiving end. These messages resemble parts of a communications session. Network layer protocols attach routing information, which may be a complete path through a network or some priority value that indicates which path the packet should take. The network layer information added by the sender can only be read by the router or the receiver's network layer protocol. Repeaters and bridges cannot recognize network layer information and can only transmit and forward packets.
