[网络协议]华为设备配置对接收和发布的路由进行过滤

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 20
   [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 20
   [LSW3]vlan batch 20
   [LSW3-GigabitEthernet0/0/2]port link-type trunk
   [LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 20

2. 配置各VLANIF接口的IP地址
   [LSW1-Vlanif10]ip add 10.1.1.1 24
   [LSW2-Vlanif10]ip add 10.1.1.2 24
   [LSW2-Vlanif20]ip add 10.1.1.2 24
   [LSW3-Vlanif20]ip add 10.1.2.3 24

3. 配置OSPF基本功能
   [LSW1]ospf 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
   [LSW2-ospf-1]area 0
   [LSW2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
   [LSW2-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255
   [LSW3]ospf 1
   [LSW3-ospf-1]area 0
   [LSW3-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255

4. 在LSW3配置5条静态路由，并在将这些静态路由引入到OSPF协议中
   [LSW3]ip route-static 172.16.16.0 24 NULL 0
   [LSW3]ip route-static 172.16.17.0 24 NULL 0
   [LSW3]ip route-static 172.16.18.0 24 NULL 0
   [LSW3]ip route-static 172.16.19.0 24 NULL 0
   [LSW3]ip route-static 172.16.20.0 24 NULL 0
   [LSW3]ospf 1
   [LSW3-ospf-1]import-route static
   

5. 配置路由发布策略
   [LSW3]ip ip-prefix 3to2 index 10 permit 172.16.17.0 24
   [LSW3]ip ip-prefix 3to2 index 20 permit 172.16.18.0 24
   [LSW3]ip ip-prefix 3to2 index 30 permit 172.16.19.0 24
   [LSW3]ospf 1
   [LSW3-ospf-1]filter-policy ip-prefix 3to2 export static
   

6. 配置路由接收策略
   [LSW1]ip ip-prefix 2to1 index 10 permit 172.16.18.0 24
   [LSW1]ospf
   [LSW1-ospf-1]filter-policy ip-prefix 2to1 import
