the MAC address is unavailable for the destination host, the router supplies its MAC address in order to get the packet. Then the router can forward the ARP request (based on the destination IP address) to the proper subnet for delivery. Create flowcharts for the following processes: 1.ARP 2.RARP 3.BOOTP 4.DHCP 4Routable Protocols 11.4.1Routed protocolsIP is a network layer protocol, and because of that, it can be routed over an internetwork, which is a network of networks. Protocols that provide support for the network layer are called routed or routable protocols4Routable Protocols 11.4.2Other routed protocolsThe focus of this course is on the most commonly used routable protocol, which is IP. Even though you will concentrate on IP, it is important to know that there are other routable protocols. Two of them are IPX/SPX and AppleTalk. Protocols such as IP, IPX/SPX and AppleTalk provide Layer 3 support and are, therefore, routable. However, there are protocols that do not support Layer 3; these are classed as non-routable protocols. The most common of these non-routable protocols is NetBEUI. NetBEUI is a small, fast, and efficient protocol that is limited to running on one segmentIn order for a protocol to be routable, it must provide the ability to assign a network number, as well as a host number, to each individual device. Some protocols, such as IPX, only require that you assign a network number; they use a host's MAC address for the physical number. Other protocols, such as IP, require that you provide a complete address, as well as a subnet mask. The network address is obtained by ANDing the address with the subnet mask. Routing protocols (Note: Do not confuse with routed protocols.) determine the paths that routed protocols follow to their destinations. Examples of routing protocols include the Routing Information Protocol (RIP), the Interior Gateway Routing Protocol (IGRP), the Enhanced Interior Gateway Routing Protocol (E...
