锐捷交换机如何配置浮动路由

01-30

一、组网要求

1) 交换机连接两个出口路由器,172.6.1.2为主线路,172.16.2.2为备用线路;

2)当主线路的物理线路失效,备用线路切换为主。

二、组网拓扑

锐捷交换机如何配置浮动路由

三、配置要点

  • 配置接口地址
  • 配置浮动路由

四、配置步骤

注意:配置之前建议使用 Ruijie#show interface status查看接口名称,常用接口名称有FastEthernet(百兆)、GigabitEthernet(千兆)和TenGigabitEthernet(万兆),以下配置以千兆接口为例

1)配置接口地址

Ruijie>enable

Ruijie#configure terminal

Ruijie(config)# interface GigabitEthernet 0/3

Ruijie(config-if-GigabitEthernet 0/3)#  no switchport  ----->把接口属性改成路由接口

Ruijie(config-if-GigabitEthernet 0/3)#ip address 172.16.1.1 255.255.255.0  ----->配置地址

Ruijie(config)#interface GigabitEthernet 0/4

Ruijie(config-if-GigabitEthernet 0/4)#no switchport

Ruijie(config-if-GigabitEthernet 0/4)#ip address 172.16.2.1 255.255.255.0

2)配置浮动路由

Ruijie(config)#ip route 0.0.0.0 0.0.0.0 172.16.1.2

Ruijie(config)#ip route 0.0.0.0 0.0.0.0 172.16.2.2 10  -----10为metric值,metric值越大优先级越低。默认是1

3) 保存配置

Ruijie(config)#end

Ruijie#write       ----->  确认配置正确,保存配置

五、验证命令:

正常情况下:

Ruijie#show ip route

Codes:  C - connected, S - static, R - RIP, B - BGP

O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default

Gateway of last resort is 172.16.1.2 to network 0.0.0.0

S*   0.0.0.0/0 [1/0] via 172.16.1.2  

C    172.16.1.0/24 is directly connected, GigabitEthernet 0/14

C    172.16.1.1/32 is local host.

C    172.16.2.0/24 is directly connected, GigabitEthernet 0/15

C    172.16.2.1/32 is local host.

当主线路down后:

Ruijie(config)#show ip route

Codes:  C - connected, S - static, R - RIP, B - BGP

O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default

Gateway of last resort is 172.16.2.2 to network 0.0.0.0

S*   0.0.0.0/0 [10/0] via 172.16.2.2

C    172.16.1.0/24 is directly connected, GigabitEthernet 0/14

C    172.16.1.1/32 is local host.

C    172.16.2.0/24 is directly connected, GigabitEthernet 0/15

C    172.16.2.1/32 is local host.
