实验2：基于源地址策略路由

 

 

 

 

R6(config)#in e0

R6(config-if)#ip add 10.1.1.254 255.255.255.0

R6(config-if)#ip add 10.1.1.2 255.255.255.0 secondary   在e0下定义一个辅助IP地址，用于模拟教师机IP。

R6(config-if)#ip add 10.1.1.3 255.255.255.0 sec         

 

R6(config)#access-list 1 permit 10.1.1.2 0.0.0.0   定义一个标准访问列表1，指定源地址为教师机。

R6(config)#access-list 2 permit 10.1.1.3 0.0.0.0  

R6(config)#route-map network1 permit 123

R6(config-route-map)#match ip address 1   当IP地址符合访问列表1中定义的源地址时，进行策略路由。

R6(config-route-map)#set ip next-hop 192.186.12.7

R6(config-route-map)#exit

R6(config)#route-map network1 permit 126

R6(config-route-map)#match ip address 2

R6(config-route-map)#set ip next-hop 192.138.21.7

R6(config-route-map)#int e0

R6(config-if)#ip policy route-map network1

R6(config-if)#exit

R6(config)#ip local policy route-map network1

R6#debug ip policy

Policy routing debugging is on

R6#ping                    扩展ping

Protocol [ip]:            默认协议IP协议

Target IP address: 7.7.7.7    目的地地址

Repeat count [5]:         发送ping的数据包数量，默认5个。

Datagram size [100]:      ping的数据包的大小，单位字节。

Timeout in seconds [2]:   延迟2秒。

Extended commands [n]: y   是否使用扩展ping命令，输入 “ y ” ，下面就会让你输入源地址。

Source address or interface: 10.1.1.3

Type of service [0]:

Set DF bit in IP header? [no]:

Validate reply data? [no]:

Data pattern [0xABCD]:

Loose, Strict, Record, Timestamp, Verbose[none]:

Sweep range of sizes [n]:

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 7.7.7.7, timeout is 2 seconds:

Packet sent with a source address of 10.1.1.3

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 44/44/44 ms
