Configure the static route:ip route 192.168.3.0 255.255.255.0 192.168.2.2 and end.View the static route: show ip route. Make sure that 192.168.3.0/24 shows up in the routing table as a static route (S).9. From Host-3, ping the fa0/0 interface of the 3620-1.Choose Host-3. Access Host-3 and ping the fa0/0 interface of the 3620-1 router:ping 192.168.1.1. The ping should be successful. Ping Host-1 ping 192.168.1.10. The ping should be successful.10. From Host-3, ping Host-1.Choose Host-3: ping 192.168.1.10. The ping should be successful.EXERCISE 9 Basic IP and Routing Troubleshooting1. Test connectivity from Host-1 to Host-3.On Host-1, ping Host-3: ping 192.168.3.10. Note that the ping fails.2. Examine the IP configuration on Host-1.Execute winipcfg. Make sure the IP addressing information is correct: IP address of 192.168.1.10,subnet mask of 255.255.255.0, and default gateway address of 192.168.1.1. 3. Test connectivity from Host-1 to its default gateway.Ping the default gateway address: ping192.168.1.1. The ping should be successful, indicating that at least layer 3 is functioning between Host-1 and the 2600.4. Verify Host-3’s IP configuration.Execute winipcfg. Make sure the IP addressing information is correct: IP address of 192.168.3.10,subnet mask of 255.255.255.0, and default gateway address of 192.168.3.1. 5. Test connectivity from Host-3 to its default gateway.At the Host-3. ping192.168.3.1. The ping should still fail, indicating that there is a problem between Host-3 and the 3620-2. In this sample, assume layer 2 is functioning correctly; therefore, it must be a problem with the 3620-2.6. Check the 3620-2’s IP configuration.From the 3620-2,ping Host-3: ping192.168.3.10. The ping should still fail. Examine the interface on the 3620-2:show interface fa0/0.The interface is disabled, but it has the correct IP address: 192.168.3.1.7.Access Host-1 and retry pinging Host-3.From the Host-1,ping Host-3: ping192.168.3.10. The ping should still fail. So far,there is connectivity within 192.168.1.0 and 192.168.3.0,but there is still a problem between these two networks.8. Check the interface statuses on the 3620-1 and verify connectivity to the 3620-2. On 3620-1:show ip interface brief. Notice that the fa0/0 and s1/1 are both up.Try pinging the 3620-2’s s1/1 interface: ping192.168.2.2. The ping fails. Examine CDP information that the 3620-1 has learned about the 3620-2:show cdp entry 3620-2.Notice that the 3620-2 has no IP address.9. Fix the IP addressing problem on the 3620-2 and retest connectivity across the serial connection.At 3620-2. Fix the IP address: configure terminal, interface serial 1/1, ip address 192.168.2.2 255.255.255.0, end. Retest the connection to the 3620-1: ping192.168.2.1. The ping should be successful.10. Examine the routing table on the 3620-2 and verify that 192.1681.0/24 shows up as a static route.Examine the routing table: show ip route. As you can see, 192.168.1.0 shows up as a static route and points to 192.168.2.1.11. Access Host-3 and try connectivity between its default gateway and the 3620-1 router.At the Host-3. Test the connection to the 3620-2: ping192.168.3.1.The ping should be successful, considering that we already tested it.Test connectivity to the 3620-1: ping 192.168.2.1. The ping should fail. This presents an interesting problem. Host-1 can ping the 3620-1. The 3620-1 can ping the 3620-2. Host-3 can ping the 3620-2.So, on a hop-by-hop basis, you have IP connectivity. The 3620-2 can even ping Host-1, indicating that some routing functioning is working.12. Access the 3620-1 router and examine its routing table. Fix the problem.Choose 3620-1. Examine the routing table: show ip route. Does the 3620-1 know how to reach 192.168.3.0/24?It does not. The 3620-2 router could ping Host-1 since the 3620-1 router is directly connected to these segments; but any traffic from the 3620-1 to 192.168.3.0/24 will fail since the router doesn’t have a path. Add a static route to 192.168.3.0/24: ip route192.168.3.0 255.255.255.0192.168.2.2. Test connectivity to Host-3: ping 192.168.3.10. The ping should be successful.13.

网络规划与设计课程设计报告
网络规划与设计课程设计课程名称网络规划与设计题目名称企业(园区)网络规划设计专业班级 17网工6班学号 08、24、26、32、40、51学生姓名指导老师易辉艳设计时间 2020/10/26-2020/10/30一、设计背景概述在今天竞争激烈的市场环境下,许多中小型企业都在追求高效的管理与沟通方法,发展跨地区、跨国业务,促进客户服务,增强企业的市场竞争力。
特别在当今信息化的现代社会,企业的运作模式也发生了根本性变化。
建设企业网络来提高企业运作效率的做法越来越普及。
所以近年来,许多中小型企业都建立了自己的网络,但是,由于许多中小企业的决策者对网络的应用和管理,在认识上存有一定的局限,以及受到现有企业条件和信息技术力量的局限,往往会在用网,尤其是在如可管理好企业的网络、挖掘和整合企业网络资源优势、为企业发展核心业务服等诸多方面,还存有许多不尽如入意的地方,致使不少中小企业的网络系统,从建立网络,到应用网络,直至管理网络,都缺乏一个科学性、有序化和规范化的发展态势,甚至直接影响乃至制约着企业核心业务的持续发展。
所以一个良好的中小型网络成为了企业发展好坏的决定因素。
