[CCNA实验报告]二:Telnet远程登陆与CDP命令操作

实验要求:
1.设置路由器名：CCNA1 CCNA2 CCNA3
2.设置password为cisco1,secret为cisco2,vty为cisco3,并要求所有密码都加密。
3.设置R1的S1/0的IP为192.168.1.1掩码24位，R2的S1/0的IP地址为192.168.1.2，掩码24位，S1/1的IP地址为192.168.2.1掩码24位，R3的S1/0 IP地址为192.168.2.2掩码24位
4.要求R1能TELNET到R2



实验过程：
配置R1
en
conf t
host ccna1                                                   设置路由器名
enable password cisco1                                        设置password
enable secret cisco2                                           设置secret
line vty 0 4                                                                                                                
login
pass cisco3                                                  设置vty密码
exit
service password-en                                           对密码加密
int s1/0
ip add 192.168.1.1 255.255.255.0                               设置s1/0
clock rate 128000
no shut
exit
exit

配置R2
En
Conf t
host ccna2                                                   设置路由器名
enable password cisco1                                        设置password
enable secret cisco2                                           设置secret
line vty 0 4                                                                                                                
login
pass cisco3                                                  设置vty密码
exit
service password-en                                           对密码加密
int S1/0                                                       设置s1/0
ip add 192.168.1.2 255.255.255.0                              
clock rate 128000
no shut
exit
int s1/1                                                          设置s1/1
ip add 192.168.2.1 255.255.255.0
no shut
exit
exit

配置R3
en
conf t
host ccna3                                                  设置路由器名
enable password cisco1                                        设置password
enable secret cisco2                                           设置secret
line vty 0 4                                                                                                                
login
pass cisco3                                                  设置vty密码
exit
service password-en                                           对密码加密
int s1/0                                                      设置s1/0
ip add 192.168.2.2 255.255.255.0
no shut
exit
exit

在R2上操作：
show cdp neighbors                                       显示相连的网络器件
show cdp                                                    显示CDP信息
show cdp traffic                                 显示CDP所用的数据包的信息
show cdp entry *                               显示所有相邻路由器的所有信息
show cdp entry WORD(路由器名)                      显示该路由器的所有信息
un all                                                 关闭所有DEBUG信息
(config)#cdp run                                              启动CDP协议
disconnect (端口号)                                        放弃该端口的连接
show cdp interface  (端口)                              显示该端口的CDP信息
clear cdp counter                                            清除CDP计数器
debug cdp packet                                    启动CDP数据包调试模式

在R1在操作
telnet 192.168.1.2                   远程登陆到R2输入在R2上设置VTY的密码
