[LSW4-Vlanif20]ip add 10.1.2.4 24

[LSW4-Vlanif30]ip add 10.1.3.4 24

[LSW4-Vlanif100]ip add 172.16.1.4 24

2. 配置LSW3的二层转发功能

[LSW3]vlan batch 10

[LSW3-GigabitEthernet0/0/1]port link-type hybrid  

[LSW3-GigabitEthernet0/0/1]port hybrid untagged vlan 10

[LSW3-GigabitEthernet0/0/1]port hybrid pvid vlan 10

[LSW3-GigabitEthernet0/0/2]port link-type hybrid        

[LSW3-GigabitEthernet0/0/2]port hybrid untagged vlan 10

[LSW3-GigabitEthernet0/0/2]port hybrid pvid vlan 10    

3. 配置OSPF协议进行互联

[LSW1]ospf 1

[LSW1-ospf-1]area 0

[LSW1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSW1-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSW2]ospf 1

[LSW2-ospf-1]area 0

[LSW2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255

[LSW2-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255

[LSW4]ospf 1

[LSW4-ospf-1]area 0

[LSW4-ospf-1-area-0.0.0.0]network 172.16.1.0 0.0.0.255

[LSW4-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

[LSW4-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255

4. 配置VRRP备份组

[LSW1]int Vlanif 10

[LSW1-Vlanif10]vrrp vrid 1 virtual-ip 10.1.1.254  

[LSW1-Vlanif10]vrrp vrid 1 priority 120

[LSW1-Vlanif10]vrrp vrid 1 preempt-mode timer delay 20

[LSW1-Vlanif10]vrrp vrid 2 virtual-ip 10.1.1.253

[LSW2]int Vlanif 10

[LSW2-Vlanif10]vrrp vrid 2 virtual-ip 10.1.1.253

[LSW2-Vlanif10]vrrp vrid 2 priority 120

[LSW2-Vlanif10]vrrp vrid 2 preempt-mode timer delay 20

[LSW2-Vlanif10]vrrp vrid 1 virtual-ip 10.1.1.254

5. 配置静态BFD会话

[LSW1]bfd  

[LSW1]bfd 1to2 bind peer-ip 10.1.1.2 interface Vlanif 10

[LSW1-bfd-session-1to2]discriminator local 1

[LSW1-bfd-session-1to2]discriminator remote 2

[LSW1-bfd-session-1to2]min-tx-interval 100

[LSW1-bfd-session-1to2]min-rx-interval 100

[LSW1-bfd-session-1to2]commit

[LSW2]bfd  

[LSW2]bfd 2to1 bind peer-ip 10.1.1.1 interface Vlanif 10

[LSW2-bfd-session-2to1]discriminator local 2

[LSW2-bfd-session-2to1]discriminator remote 1

[LSW2-bfd-session-2to1]min-rx-interval 100

[LSW2-bfd-session-2to1]min-tx-interval 100

[LSW2-bfd-session-2to1]commit

 

 

6. 配置VRRP与BFD联动功能

[LSW1]int Vlanif 10

[LSW1-Vlanif10]vrrp vrid 2 track bfd-session 1 increased 40

[LSW2]int Vlanif 10

[LSW2-Vlanif10]vrrp vrid 1 track bfd-session 2 increased 40

7. 验证配置
