华为设备配置OSPF与BFD联动

1. 配置各接口所属的VLAN

[LSW1]vlan batch 12 13

[LSW1-GigabitEthernet0/0/4]port link-type trunk  

[LSW1-GigabitEthernet0/0/4]port trunk allow-pass vlan 12

[LSW1-GigabitEthernet0/0/3]port link-type trunk  

[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 13

[LSW2]vlan batch 10 12 23

[LSW2-GigabitEthernet0/0/4]port link-type trunk  

[LSW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 12

[LSW2-GigabitEthernet0/0/3]port link-type trunk  

[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 23

[LSW2-GigabitEthernet0/0/1]port link-type trunk  

[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10

[LSW3]vlan batch 13 23

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

[LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 13

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

[LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 23

2. 配置各接口的IP地址

[LSW1-Vlanif12]ip add 10.1.12.1 24

[LSW1-Vlanif13]ip add 10.1.13.1 24

[LSW1]int LoopBack 0

[LSW1-LoopBack0]ip add 10.1.1.1 32

[LSW2-Vlanif12]ip add 10.1.12.2 24

[LSW2-Vlanif23]ip add 10.1.23.2 24

[LSW2-Vlanif10]ip add 10.1.10.2 24

[LSW2]int LoopBack 0

[LSW2-LoopBack0]ip add 10.2.2.2 32

[LSW3-Vlanif13]ip add 10.1.13.3 24

[LSW3-Vlanif23]ip add 10.1.23.3 24

[LSW3]int LoopBack 0

[LSW3-LoopBack0]ip add 10.3.3.3 32

3. 配置OSPF基本功能

[LSW1]ospf 1 router-id 10.1.1.1

[LSW1-ospf-1]area 0

[LSW1-ospf-1-area-0.0.0.0]network 10.1.12.0 0.0.0.255

[LSW1-ospf-1-area-0.0.0.0]network 10.1.13.0 0.0.0.255

[LSW2]ospf 1 router-id 10.2.2.2  

[LSW2-ospf-1]area 0

[LSW2-ospf-1-area-0.0.0.0]network 10.1.12.0 0.0.0.255

[LSW2-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255

[LSW2-ospf-1-area-0.0.0.0]network 10.1.10.0 0.0.0.255

[LSW3]ospf 1 router-id 10.3.3.3

[LSW3-ospf-1]area 0

[LSW3-ospf-1-area-0.0.0.0]network 10.1.13.0 0.0.0.255

[LSW3-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255

去往目的网段10.1.10.0/24的路由下一跳地址为10.1.12.2，说明流量在链路LSW1→LSW2上传输

4. 配置OSPF与BFD联动

[LSW1]bfd  

[LSW1]ospf  

[LSW1-ospf-1]bfd all-interfaces enable

[LSW2]bfd  

[LSW2]ospf  

[LSW2-ospf-1]bfd all-interfaces enable

[LSW3]bfd  

[LSW3]ospf  

[LSW3-ospf-1]bfd all-interfaces enable
