華爲路由器BGP聯盟詳解

 本篇文章爲大家分享下華爲路由BGP聯盟的基本配置，通過BGP聯盟最終實驗BGP內部鄰居之間路由條目的傳遞，最終實現網絡互通。
     實驗拓撲圖如下：

實驗說明:
    路由器R2、R3、R4、R5路由器所在配置爲聯盟區域，聯盟AS號碼爲200，R1的AS號爲100，R6的AS號爲600。

實驗要求：
    1.IBGP通過迴環口建立鄰居；
    2.EBGP通過直連接口建立鄰居。
    3.最終實現R1的 LoopBack0接口和R6的 LoopBack0接口網絡互通。

每個基本網絡配置：

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路由器通過內部網關協議（IGP）OSP實現內網互通，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

驗證測試：R1的 LoopBack0接口和R6的 LoopBack0接口網絡互通。
結果如下圖：

驗證成功！！！
