工作任务描述
两个企业位于同一栋大楼，要求将两个公司的现有网络（独立子网）相互连接，以实现双方信息交流，资源共享的目的 。
工作任务实施
1.网络拓扑结构设计（粘贴PT的拓扑图，要有IP地址的规划信息）
2.设备配置命令（各个路由器分别配置）
Router>en
Router#
Router#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface f0/0
Router(config-if)#
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#
Router(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#exit
Router(config)#
Router(config)#interface f0/1
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
Router(config-if)#
Router(config-if)#
3.单段测试结果
Router#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
Router#ping 192.168.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.2.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
4. 综合测试结果
5. 查看路由器的路由
Router#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
C 192.168.1.0/24 is directly connected, FastEthernet0/0
C 192.168.2.0/24 is directly connected, FastEthernet0/1
Router#
6. 查看路由器的接口状态
Router#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.1.1 YES manual up up
FastEthernet0/1 192.168.2.1 YES manual up up
Router#
7.查看路由器的当前配置文件、
Router#show running-config

工作扩展
配置路由器的telnet远程调试功能，使用的登陆密码和特权密码都为cisco，写出配置命令。
Router#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#enable password cisco
Router(config)#enable secret cisco
Router(config)#hostname R1
R1(config)#line vty 0 4
R1(config-line)#login
% Login disabled on line 66, until ‘password‘ is set
% Login disabled on line 67, until ‘password‘ is set
% Login disabled on line 68, until ‘password‘ is set
% Login disabled on line 69, until ‘password‘ is set
% Login disabled on line 70, until ‘password‘ is set
R1(config-line)#password cisco
PC>telnet 192.168.1.1

1.单段测试不成功的原因？
添加IP后没有 no shutdown
防火墙未阻挡
2.整体测试不成功的原因？
防火墙阻挡
没有添加网关
3.基于路由器的网络互联设计的注意事项是什么？
注意IP的分配
