Huawei equipment is configured with OSPF and BFD linkage

1. Configure all interfaces 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. Configure the IP Address
   [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. To configure OSPF Basic function
   [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
   
   

Go to the destination segment 10.1.10.0/24 The next hop address of the route is 10.1.12.2, The traffic is on the link LSW1→LSW2 Up transfer
4. To configure OSPF And BFD linkage
[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. Check the configuration ： Yes LSW2 Of GE0/0/4 Interface execution shutdown command , Analog link failure
