CISCO 路由器启动自动配置

【实验拓扑】

【实验要求】

1、首先按照上图配置好网络，并设置静态路由使得R1与R5之间能够互通

2、将R5的当前配置文件拷贝到R1的flash中

3、在R1上开启tftp-server，文件为flash中R5的配置

4、在R1上开启DNS，并将R5主机名对应R5的IP地址

5、不保存R5的配置，重启R5，使得配置能够自动从R1中获得

【实验配置】

按照“实验基本配置”配置好网络，然后按照下面步骤操作

R5#conf t

R5(config)#tftp-server system:running-config alias R5.cfg

R1#copy tftp flash:

Address or name of remote host []? 155.1.0.5

Source filename []? R5.cfg

Destination filename [R5.cfg]?

Accessing tftp://155.1.0.5/R5.cfg...

Erase flash: before copying? [confirm]n

Loading R5.cfg from 155.1.0.5 (via FastEthernet0/0): !

[OK - 1263 bytes]

Verifying checksum... OK (0x9A03)

1263 bytes copied in 4.948 secs (255 bytes/sec)

R4:

interface Serial 0/0

ip helper-address 155.1.146.1

R1:

tftp-server flash:R5.cfg alias r5-confg

ip dns server

ip host R5 155.1.0.5

R5#wr era

Erasing the nvram filesystem will remove all configuration files! Continue?

[confirm]

[OK]

Erase of nvram: complete

R5#reload

System configuration has been modified. Save? [yes/no]: no

Proceed with reload? [confirm]

……

Would you like to enter the initial configuration dialog? [yes/no]:

Press RETURN to get started!
