Dr selection of OSPF configuration for Huawei devices

1. Configure all interfaces VLAN
   [LSW1]vlan 10
   [LSW1-GigabitEthernet0/0/1]port link-type trunk
   [LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW2]vlan batch 10
   [LSW2-GigabitEthernet0/0/1]port link-type trunk
   [LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW3]vlan 10
   [LSW3-GigabitEthernet0/0/1]port link-type trunk
   [LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW4]vlan 10
   [LSW4-GigabitEthernet0/0/1]port link-type trunk
   [LSW4-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW5]vlan 10
   [LSW5-GigabitEthernet0/0/1]port link-type trunk
   [LSW5-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW5-GigabitEthernet0/0/2]port link-type trunk
   [LSW5-GigabitEthernet0/0/2]port trunk allow-pass vlan 10
   [LSW5-GigabitEthernet0/0/3]port link-type trunk
   [LSW5-GigabitEthernet0/0/3]port trunk allow-pass vlan 10
   [LSW5-GigabitEthernet0/0/4]port link-type trunk
   [LSW5-GigabitEthernet0/0/4]port trunk allow-pass vlan 10

2. Configure the IP Address
   [LSW1-Vlanif10]ip add 10.1.1.1 24
   [LSW2-Vlanif10]ip add 10.1.1.2 24
   [LSW3-Vlanif10]ip add 10.1.1.3 24
   [LSW4-Vlanif10]ip add 10.1.1.4 24
   [LSW1]int LoopBack 0
   [LSW1-LoopBack0]ip add 10.10.1.1 32
   [LSW2]int LoopBack 0
   [LSW2-LoopBack0]ip add 10.10.2.2 32
   [LSW3]int LoopBack 0
   [LSW3-LoopBack0]ip add 10.10.3.3 32
   [LSW4]int LoopBack 0
   [LSW4-LoopBack0]ip add 10.10.4.4 32

3. To configure OSPF Basic function
   [LSW1]ospf 1 router-id 10.10.1.1
   [LSW1-ospf-1]area 0
   [LSW1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   [LSW2]ospf 1 router-id 10.10.2.2
   [LSW2-ospf-1]area 0
   [LSW2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   [LSW3]ospf 1 router-id 10.10.3.3
   [LSW3-ospf-1]area 0
   [LSW3-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   [LSW4]ospf 1 router-id 10.10.4.4
   [LSW4-ospf-1]area 0
   [LSW4-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   

4. Configure on the switch interface DR priority
   [LSW1-Vlanif10]ospf dr-priority 100 // Was elected DR
   [LSW2-Vlanif10]ospf dr-priority 0 // Can't be DR or BDR
   [LSW3-Vlanif10]ospf dr-priority 2 // Was elected BDR

5. restart OSPF process
   reset ospf process
   reset ospf process
   reset ospf process
   reset ospf process

6. Verify configuration
