本篇文章为大家分享下华为路由BGP联盟的基本配置，通过BGP联盟最终实验BGP内部邻居之间路由条目的传递，最终实现网络互通。
	 实验拓扑图如下：


实验说明:
	路由器R2、R3、R4、R5路由器所在配置为联盟区域，联盟AS号码为200，R1的AS号为100，R6的AS号为600。
	
实验要求：
	1.IBGP通过回环口建立邻居；
	2.EBGP通过直连接口建立邻居。
	3.最终实现R1的 LoopBack0接口和R6的 LoopBack0接口网络互通。
	
每个基本网络配置：

R1 sysname R1 interface g0/0/0 ip address 192.168.12.1 24 interface LoopBack 0 ip address 10.10.1.1 24 quit R2 sysname R2 interface g0/0/1 ip address 192.168.12.2 24 interface g0/0/0 ip address 192.168.23.2 24 quit interface LoopBack 0 ip address 10.10.2.2 24 quit R3 sysname R3 interface g0/0/1 ip address 192.168.23.3 24 interface g0/0/0 ip address 192.168.34.3 24 interface LoopBack 0 ip address 10.10.3.3 24 quit R4 sysname R4 interface g0/0/1 ip address 192.168.34.4 24 interface g0/0/0 ip address 192.168.45.4 24 interface LoopBack 0 ip address 10.10.4.4 24 quit R5 sysname R5 interface g0/0/1 ip address 192.168.45.5 24 interface g0/0/0 ip address 192.168.56.5 24 quit interface LoopBack 0 ip address 10.10.5.5 24 quit R6 sysname R6 interface g0/0/1 ip address 192.168.56.6 24 interface LoopBack 0 ip address 10.10.6.6 24 quit

路由器R2、R3、R4、R5路由器通过内部网关协议（IGP）OSP实现内网互通，配置如下：

R2 ospf 1 router-id 2.2.2.2 area 0 network 192.168.23.0 0.0.0.255 network 10.10.2.0 0.0.0.255 quit quit R3 ospf 1 router-id 3.3.3.3 area 0 network 192.168.23.0 0.0.0.255 network 192.168.34.0 0.0.0.255 network 10.10.3.0 0.0.0.255 quit quit R4 ospf 1 router-id 4.4.4.4 area 0 network 192.168.45.0 0.0.0.255 network 192.168.34.0 0.0.0.255 network 10.10.4.0 0.0.0.255 quit quit R5 ospf 1 router-id 5.5.5.5 area 0 network 192.168.45.0 0.0.0.255 network 10.10.5.0 0.0.0.255 quit quit

BGP配置：BGP联盟
配置命令如下：

R1 bgp 100 router-id 1.1.1.1 peer 192.168.12.2 as-number 200 network 10.10.1.0 255.255.255.0 quit R2 bgp 64523 router-id 2.2.2.2 confederation id 200 peer 192.168.12.1 as-number 100 peer 10.10.3.3 as-number 64523 peer 10.10.3.3 connect-interface LoopBack0 peer 10.10.3.3 next-hop-local quit R3 bgp 64523 router-id 3.3.3.3 confederation id 200 confederation peer-as 64545 peer 10.10.2.2 as-number 64523 peer 10.10.2.2 connect-interface LoopBack0 peer 10.10.4.4 as-number 64545 peer 10.10.4.4 connect-interface LoopBack0 peer 10.10.4.4 ebgp-max-hop quit R4 bgp 64545 router-id 4.4.4.4 confederation id 200 confederation peer-as 64523 peer 10.10.3.3 as-number 64523 peer 10.10.3.3 connect-interface LoopBack0 peer 10.10.3.3 ebgp-max-hop peer 10.10.5.5 as-number 64545 peer 10.10.5.5 connect-interface LoopBack0 quit R5 bgp 64545 router-id 5.5.5.5 peer 192.168.56.6 as-number 600 peer 10.10.4.4 as-number 64545 peer 10.10.4.4 connect-interface LoopBack 0 peer 10.10.4.4 next-hop-local quit R6 bgp 600 router-id 6.6.6.6 peer 192.168.56.5 as-number 200 import-route direct quit

验证测试：R1的 LoopBack0接口和R6的 LoopBack0接口网络互通。
结果如下图：


验证成功！！！
