华为设备配置BGP与IGP交互

本文主要是介绍华为设备配置BGP与IGP交互，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 配置接口所属VLAN
   [LSW1]vlan batch 10 40
   [LSW1-GigabitEthernet0/0/1]port link-type trunk
   [LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 40
   [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 30
   [LSW3-GigabitEthernet0/0/2]port link-type trunk
   [LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
   [LSW3-GigabitEthernet0/0/1]port link-type trunk
   [LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 30
2. 配置各VLANIF接口的IP地址
   [LSW1-Vlanif10]ip add 10.1.1.1 24
   [LSW1-Vlanif40]ip add 10.1.4.1 24
   [LSW2-Vlanif10]ip add 10.1.1.2 24
   [LSW2-Vlanif20]ip add 10.1.2.2 24
   [LSW3-Vlanif20]ip add 10.1.2.3 24
   [LSW3-Vlanif30]ip add 10.1.3.3 24
3. 配置OSPF
   [LSW2]ospf 1
   [LSW2-ospf-1]area 0
   [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
   [LSW3-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255
4. 配置EBGP连接
   [LSW1]bgp 65008
   [LSW1-bgp]router-id 10.1.1.1
   [LSW1-bgp]peer 10.1.1.2 as-number 65009
   [LSW1-bgp]ipv4-family unicast
   [LSW1-bgp-af-ipv4]network 10.1.4.0 255.255.255.0
   [LSW2]bgp 65009
   [LSW2-bgp]router-id 10.2.2.2
   [LSW2-bgp]peer 10.1.1.1 as-number 65008
5. 配置BGP与IGP交互
   [LSW2]bgp 65009
   [LSW2-bgp]ipv4-family unicast
   [LSW2-bgp-af-ipv4]import-route ospf 1 //配置BGP引入OSPF路由
   

[LSW2]ospf 1
[LSW2-ospf-1]import-route bgp

6. 配置路由自动聚合
   [LSW2]bgp 65009
   [LSW2-bgp]ipv4-family unicast
   [LSW2-bgp-af-ipv4]summary automatic
   

7. 验证配置
