静态路由及默认路由

拓扑图

 

场景，通过配置，使R1,R2,R3之间互联互通

1、配置R1,R2,R3设备名称和IP地址

R1配置

system-view

sysname r1

interface serial 4/0/0

ip address 10.0.12.1 24

description this port connect to r2-s4/0/0 //与路由器2serial接口进行连接通信

quit

inteface gigabitethernet 0/0/0

ip address 10.0.13.1 24

description this port connect to r3-g0/0/0 //与路由器3接口进行连接通信

interface loopback 0 //进入回环接口地址

ip address 10.0.1.1 24

 

配置完成后检查配置是否生效

display current-configuration

R2的配置

system-view

sysname r2

interface serial 4/0/0

ip address 10.0.12.2 24

description this port connect to r1-s4/0/0

quit

interface serial 4/0/1

ip address 10.0.23.2 24

desciption this port connect to r3-s4/0/1

quit

interface loopback 0

ipaddress 10.0.2.2 24

display current-configuration

R3的配置

system-view

sysname r3

interface serial 4/0//1

ip address 10.0.23.3 24

description this port connect to r2-s4/0/1

quit

interface gigabitethernet 0/0/0

ip address 10.0.13.3 24

description this port connect to r1-g0/0/0

quit

interface loopback 0

ip address 10.0.3.3 24

dis current-configuration

配置完成后各端口下IP地址及信息

R1 serial 4/0/0 10.0.12.1 int gi 0/0/0 10.0.13.1 loopback 10.0.1.1

R2 serial 4/0/0 10.0.12.2 serial 4/0/1 10.0.23.2 loopback 10.0.2.2

R3 serial 4/0/1 10.0.23.3 int gi 0/0/0 10.0.13.3 loopback 10.0.3.3

R1 S4/0/0-----R2 S4/0/0 R1 int gi 0/0/0 --------R3 int gi 0/0/0

R3 S4
