靜態路由

        Hi，你們好，愚人節快樂，今天我給你們帶來的是「Cisco靜態路由+默認路由實現全網互通」

1、實驗拓補

 

2、實驗環境

三個Cisco路由器(R1,R2,R3)， 每臺路由器啓用Loopback虛擬接口用於扮演PC機

 

3、實驗目的

實現全網互通，每臺路由器都能ping通全部接口（包括虛擬接口）

 

4、配置步驟

R1上配置

R1#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#interface serial 1/0

R1(config-if)#clock rate 64000

R1(config-if)#ip address 1.1.1.1 255.255.255.0

R1(config-if)#no shutdown

*Mar  1 00:02:23.743: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up

*Mar  1 00:02:24.747: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial

R1(config-if)#exit

R1(config)#interface loopback 0

*Mar  1 00:03:35.187: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up

R1(config-if)#ip address 10.10.10.10 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#exit

R2上配置

R2#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

R2(config)#interface serial 1/0

R2(config-if)#ip address 1.1.1.254 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

*Mar  1 00:03:36.279: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up

*Mar  1 00:03:37.283: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up

R2(config-if)#ip address 2.2.2.1 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

*Mar  1 00:05:43.735: %LINK-3-UPDOWN: Interface Serial1/1, changed state to up

*Mar  1 00:05:44.739: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1, changed state to up

R2(config)#interface loopback 0

R2(config-if)#ip address 20.20.20.20 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

R3上配置

R3#configure terminal

R3(config)#interface serial 1/0

R3(config-if)#ip address 2.2.2.254 255.255.255.0

R3(config-if)#no shutdown

*Mar  1 00:06:26.323: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up

*Mar  1 00:06:27.327: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up

R3(config-if)#exit

R3(config)#interface loopback 0

*Mar  1 00:07:12.331: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up

R3(config-if)#ip address 30.30.30.30 255.255.255.0

R3(config-if)#no shutdown

R3(config-if)#exit

 

配置路由條目

R1(config)#ip route 0.0.0.0 0.0.0.0 1.1.1.254

R2(config)#ip route 10.10.10.0 255.255.255.0 1.1.1.1

R2(config)#ip route 30.30.30.0 255.255.255.0 2.2.2.254

R3(config)#ip route 0.0.0.0 0.0.0.0 2.2.2.1
