Configuring OSPF GR features for Huawei devices

1. Configure all interfaces VLAN
   [LSW1]vlan batch 10
   [LSW1-GigabitEthernet0/0/2]port link-type trunk
   [LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10
   [LSW2]vlan batch 10 100
   [LSW2-GigabitEthernet0/0/1]port link-type trunk
   [LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW2-GigabitEthernet0/0/3]port link-type trunk
   [LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 100
   [LSW3]vlan 100
   [LSW3-GigabitEthernet0/0/2]port link-type trunk
   [LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 100
2. Configure the IP Address
   [LSW1-Vlanif10]ip add 10.1.10.1 24
   [LSW1]int LoopBack 0
   [LSW1-LoopBack0]ip add 10.1.1.1 32
   [LSW2-Vlanif10]ip add 10.1.10.2 24
   [LSW2-Vlanif100]ip add 10.1.100.2 24
   [LSW2]int LoopBack 0
   [LSW2-LoopBack0]ip add 10.2.2.2 32
   [LSW3-Vlanif100]ip add 10.1.100.3 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 10.1.10.0 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 10.1.10.0 0.0.0.255
   [LSW2-ospf-1]area 100
   [LSW2-ospf-1-area-0.0.0.100]network 10.1.100.0 0.0.0.255
   [LSW3]ospf 1 router-id 10.3.3.3
   [LSW3-ospf-1]area 100
   [LSW3-ospf-1-area-0.0.0.100]network 10.1.100.0 0.0.0.255
4. Can make Opaque-LSA function , Realization OSPF adopt Type9 LSA Support OSPF GR
   [LSW2]ospf 1
   [LSW2-ospf-1]opaque-capability enable
   [LSW1]ospf
   [LSW1-ospf-1]opaque-capability enable
5. To configure OSPF GR characteristic , Make running OSPF The normal forwarding of data will not be affected during the restart of the Protocol
   [LSW2-ospf-1]graceful-restart
   [LSW1-ospf-1]graceful-restart
6. Verify configuration
   
   

reset ospf process graceful-restart // Smooth restart LSW1 Of OSPF process

You can see LSW1 And LSW2 The neighborhood relationship continues to be Full state , Not subject to LSW1 Of OSPF The impact of smooth restart of the process
