ccna 200 301 syllabus plural of sheep.Default routing (Default routing) is also called default routing in some documents, some do not use the default route in the routing table can forward that in the storage listed out of the remote destination network packets to the next-hop router. Networks that are connected to their neighboring networks, into, root network (only one connection can be used out of this network are only one way to go) for only one connection between these networks and the outside world. As shown in the default route, because 5-4-1 shows a company's network topology, the company through the router access ISP,through the ISP router218.1.1.1 accesses the entire Intemeto If you are using a class-based static route, you need to add all the Class A, Class B, and Class C IP addresses on the company's egress router, and a typical low-end router simply cannot handle so many routing entries. For the network topology in Figure 5-4-1, the best way to configure the company router is to use a default route, which is similar to a static route, except that the network address and subnet mask are changed to "0.0Q00.0.0.0", or 8 zeros. the default route for the company's outbound router is configured as follows.Router(config)#ip route 0.0.0.00.0.0.0.0 218.1.1.1 Actually, not only static routes are used on the stub network, but statistically 99.9% of routers on the Internetware uses a default route. The default route was used in the configuration in Section 4.4.1 and can be used in the configuration in Figure 5-2-1 in Section 5.2 of this chapter. Use the "show running-confign" command on routers Rl, R2, and R3 to view the configuration of the routers, and use the command preceded by "no" to cancel all "ip route" commands. Here is a way to cancel the configuration, you can copy the relevant configuration and then replace "ip route" with "no ip route" in Notepad, then copy and paste it back to the router. After canceling the static route configuration command, use the following command to configure routers Rl, R2 and R3.Figure 5-4-1 Stub NetworkR2(config)#ip route R3(config)#ip routeping all the IP addresses in Figure 5-2-1 on router R1, and the results are all pingable. Use the traceroute command on router R1 to verify the flow of packets, and the results are displayed as follows:Rl#traceroute 3,3.3.3 0.0.0.0 0.0.0.012.1.1.2 All unknown packets on R1 are sent to router R2 ° 0.0.0.0 0.0 0.0.0.0 23.1.1.3 All unknown packets on R2 are sent to router R3. 0.0.0.0 0.0.0.0.0.013.1.1.1 On R3 All unknown packets are sent to router RL Type escape sequence to abort. tracing theroute to3.3.3.31 12.1.1.2 20 msec 104 msec 64 msec 2 23.1.1.3 180 msec 164 msec * From the above output, we can see that router R1 forwards the unknown packets going to 3.333 to router R2, which in turn forwards the unknown packets to R3. how do the packets from R3 back to R1 flow? R3 also takes the default route and sends the packets from R1 directly back to R1, that is, in the process of pinginging R3 from R1, the Echorequest packets go around R2 and the Echoreply packets come back directly to Rl. tracerouteThe result of this command can not be seen, you can use the extended ping command to view the results, CCNA exams do not involve this knowledge, the reader to understand it can be.
