华为设备配置OSPF GR特性

1. 配置各接口所属的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. 配置各接口的IP地址
   [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. 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 10.1.10.0 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. 使能Opaque-LSA功能，实现OSPF通过Type9 LSA支持OSPF GR
   [LSW2]ospf 1
   [LSW2-ospf-1]opaque-capability enable
   [LSW1]ospf
   [LSW1-ospf-1]opaque-capability enable
5. 配置OSPF GR特性,使运行的OSPF协议重启过程中不影响数据的正常转发
   [LSW2-ospf-1]graceful-restart
   [LSW1-ospf-1]graceful-restart
6. 验证配置
   
   

reset ospf process graceful-restart //平滑重启LSW1的OSPF进程

可以看到LSW1与LSW2邻居关系继续保持为Full状态，不受LSW1的OSPF进程平滑重启的影响
