10.7 ARP This page displays the ARP table information. Choose the menu Routing→ARP→ARP Table to load the following page. Figure 10-23 ARP Table The following entries are displayed on this screen:  ARP Table Interface: IP Address: Displays the network interface of arp entry. Enter the DHCP server IP address. MAC Address: Displays the MAC address of ARP entry. Type: Displays the type of ARP entry, e.g. Static, Dynamic. Age Time(min): Displays the live time left before arp entry be deleted. 10.8 RIP Note: Router mentioned in this chapter refers to the traditional router or the switch running routing protocols. RIP (Routing Information Protocol) is intended for use within the IP-based Internet. This protocol is most useful as an Interior Gateway Protocol (IGP). RIP was designed to work with moderate-size networks using reasonably homogeneous technology. Thus it is suitable as an IGP for many campuses and for regional networks using serial lines whose speeds do not vary widely. It is not intended for use in more complex environments. RIP is a distance vector routing protocol, using UDP packets for exchanging information through port 520. RIP uses "hop" to measure the distance to a destination. The hop count from a router to a directly connected network is 0. The hop count from a router to a directly connected router is 1. To limit convergence time, the range of RIP metric value is from 0 to 15. A metric value of 16 (or greater) is considered infinite, which means the destination network is unreachable. That is why RIP is not suitable for large-scaled networks. RIP prevents routing loops by implementing the split horizon and poison reverse functions.  RIP routing table An RIP router has a routing table containing routing entries of all reachable destinations, and each routing entry contains:  Destination address: IP address of a host or a network. 168
