华为设备BGP基本配置_华为bgp配置

1. 配置各接口所属的VLAN
   [LSW1]vlan batch 10 50
   [LSW1-GigabitEthernet0/0/2]port link-type trunk
   [LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10
   [LSW1-GigabitEthernet0/0/5]port link-type trunk
   [LSW1-GigabitEthernet0/0/5]port trunk allow-pass vlan 50
   [LSW2]vlan batch 10 20 40
   [LSW2-GigabitEthernet0/0/3]port link-type trunk
   [LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 20
   [LSW2-GigabitEthernet0/0/4]port link-type trunk
   [LSW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 40
   [LSW2-GigabitEthernet0/0/1]port link-type trunk
   [LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
   [LSW3]vlan batch 20 30
   [LSW3-GigabitEthernet0/0/2]port link-type trunk
   [LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 20
   [LSW3-GigabitEthernet0/0/4]port link-type trunk
   [LSW3-GigabitEthernet0/0/4]port trunk allow-pass vlan 30
   [LSW4]vlan batch 30 40
   [LSW4-GigabitEthernet0/0/3]port link-type trunk
   [LSW4-GigabitEthernet0/0/3]port trunk allow-pass vlan 30
   [LSW4-GigabitEthernet0/0/2]port link-type trunk
   [LSW4-GigabitEthernet0/0/2]port trunk allow-pass vlan 40

2. 配置各VLANIF接口的IP地址
   [LSW1-Vlanif10]ip add 10.1.1.1 24
   [LSW1-Vlanif50]ip add 10.1.5.1 24
   [LSW2-Vlanif10]ip add 10.1.1.2 24
   [LSW2-Vlanif20]ip add 10.1.2.2 24
   [LSW2-Vlanif40]ip add 10.1.4.2 24
   [LSW3-Vlanif20]ip add 10.1.2.3 24
   [LSW3-Vlanif30]ip add 10.1.3.3 24
   [LSW4-Vlanif30]ip add 10.1.3.4 24
   [LSW4-Vlanif40]ip add 10.1.4.4 24
   [LSW1]stp disable
   [LSW2]stp disable
   [LSW3]stp disable
   [LSW4]stp disable

3. 配置IBGP连接
   [LSW2]bgp 65002
   [LSW2-bgp]router-id 2.2.2.2
   [LSW2-bgp]peer 10.1.2.3 as-number 65002
   [LSW2-bgp]peer 10.1.4.4 as-number 65002
   [LSW3]bgp 65002
   [LSW3-bgp]router-id 3.3.3.3
   [LSW3-bgp]peer 10.1.2.2 as-number 65002
   [LSW3-bgp]peer 10.1.3.4 as-number 65002
   [LSW4]bgp 65002
   [LSW4-bgp]router-id 4.4.4.4
   [LSW4-bgp]peer 10.1.3.3 as-number 65002
   [LSW4-bgp]peer 10.1.4.2 as-number 65002

4. 配置EBGP
   [LSW1]bgp 65001
   [LSW1-bgp]router-id 1.1.1.1
   [LSW1-bgp]peer 10.1.1.2 as-number 65002
   [LSW2]bgp 65002
   [LSW2-bgp]peer 10.1.1.1 as-number 65001
   

5. 配置LSW1发布路由
   [LSW1]bgp 65001
   [LSW1-bgp]ipv4-family unicast
   [LSW1-bgp-af-ipv4]network 10.1.5.0 255.255.255.0
   
   
   

从路由表可以看出，LSW3和LSW4学到了AS65001中的10.1.5.0的路由，但因为下一跳10.1.1.1不可达，所以也不是有效路由
6. 配置BGP引入直连路由
[LSW2]bgp 65002
[LSW2-bgp]ipv4-family unicast
[LSW2-bgp-af-ipv4]import-route direct

可以看出10.1.5.0的路由变为有效路由
7.验证配置
