cisco 210-060 dumps.A multimedia presentation introducing the basic configuration of IP routing protocols is included in the companion digital resource to this book.Certification Objectives 18.0318.3 RIPRIP is available in two versions: version 1 and version 2. Version 1 is a distance vector protocol and is defined in RFC1058; Version 2 improves on RIPvl and is defined in RFC1721 and 1722. Currently, the CCNA exam focuses primarily on version 2, but you still need to have some understanding of RIPvl, especially its features. This section describes the basic configuration and troubleshooting of networks that use RIP.18.3.1 How RIP worksAs stated in Chapter 14, RIP is a distance vectoring protocol, which is a relatively old protocol and therefore very stable; in other words,unlike other more advanced protocols, Cisco has not done a lot of development work for this protocol. Therefore, when upgrading to a newer version of IOS, RIP works no differently than it did in previous versions. This section briefly describes these two RIP versions.RIPvlRIPvl uses local broadcasts to share routing information. These updates are sent at regular intervals, every 30 seconds by default, while the hold time is 180 seconds. Both RIP versions use hop count as a metric, but hop count is not the best metric in all cases. For example, if there are two paths to the same network, one containing two Ethernet connections and the other containing a 64kbit/s WAN connection; the RIP will choose the slower 64kbit/s connection because the cumulative hop count is lower. You must keep this in mind when considering how the RIP will populate the router's routing table. To avoid packets going on endlessly in the loop, both RIP versions set the maximum number of hops to 15,to solve the problem of counting to infinity. After the packet reaches hop 16, it is discarded.As stated in the previous section, RIPvl is a classification protocol. It is important to keep this in mind when configuring RIP and developing a subnetting scheme: only one subnet mask can be used in a given Class A, Class B, or Class C network. For example, if you have a Class B network (such as 172.16.0.0), only one subnet mask can be used to subnet it. For example, on network 172.16.0.0, you cannot use both subnet masks 255.255.255.0 and 255.255.255.128, but only one of them.Another interesting feature is that RIP supports up to 6 equal-overhead paths to the same destination network: the router adds all 6 paths to the routing table and balances the load between them. By default, 4 equal-overhead paths are supported, but this can be changed to a maximum of 6. Don't forget that an equal-overhead path means that multiple paths to the same destination network have the same metric value. RIP does not equalize the load between paths with different overheads.
