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

5. 检查配置：对LSW2的GE0/0/4接口执行shutdown命令，模拟链路故障
