如何建立备份路由链路知识总结

如何建立备份路由链路知识总结

思路：

1.建立eNSP模型

2.基本配置（IP地址，vlan）

3.路由配置及preference配置

1.建立eNSP模型

2.基本配置（IP地址，vlan）

交换机配置

[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 10

[SW1]interface GigabitEthernet0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access
[SW1-GigabitEthernet0/0/1]port default vlan 10

[SW2]interface GigabitEthernet 0/0/2
[SW2-GigabitEthernet0/0/2]port link-type access
[SW2-GigabitEthernet0/0/2]port default vlan 40

[SW2]interface GigabitEthernet 0/0/1
[SW2-GigabitEthernet0/0/1]port link-type access
[SW2-GigabitEthernet0/0/1]port default vlan 40

路由器配置

[R1]interface GigabitEthernet 2/0/0
[R1-GigabitEthernet2/0/0]ip address 192.168.10.254 24

[R1]interface g0/0/0

[R1-GigabitEthernet0/0/0]ip address 192.168.2.1 /24
[R1]interface g0/0/1
[R1-GigabitEthernet0/0/1]ip address 192.168.3.1 24

[R2]interface g2/0/0
[R2-GigabitEthernet2/0/0]ip address 192.168.40.254 24
[R2]interface g0/0/0
[R2-GigabitEthernet0/0/0]ip address 192.168.2.2 24
[R2]interface g0/0/1
[R2-GigabitEthernet0/0/1]ip address 192.168.3.2 24

3.路由配置及preference配置

[R1]ip route-static 192.168.40.0 24 192.168.3.2 preference 80 //默认值为60,越大级别越低，即为备份链路

[R1]ip route-static 192.168.40.0 24 192.168.2.2

[R2]ip route-static 192.168.10.0 24 192.168.3.1 preference 80

[R2]ip route-static 192.168.10.0 24 192.168.2.1
