本篇文章爲大家分享下華爲路由BGP鄰居、聯盟、路由反射器綜合實驗配置，通過BGP鄰居建立、聯盟、路由反射器，實現BGP內部鄰居之間路由條目的傳遞，最終實現R1的LoopBack 0與R6的LoopBack 0網絡互通。
** 實驗拓撲圖如下：**
**第一步，基本網絡配置如下：**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 192.168.27.2 24
quit
interface LoopBack 0
ip address 10.10.2.2 24
quit
R7
sysname R7
interface g0/0/1
ip address 192.168.27.7 24
interface g0/0/0
ip address 192.168.37.7 24
interface LoopBack 0
ip address 10.10.7.7 24
quit
R3
sysname R3
interface g0/0/1
ip address 192.168.37.3 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
第二步，中間區域配置IGP路由協議OSPF，配置如下：
R2
ospf 1 router-id 2.2.2.2
area 0
network 192.168.27.0 0.0.0.255
network 10.10.2.0 0.0.0.255
quit
quit
R7
ospf 1 router-id 7.7.7.7
area 0
network 192.168.37.0 0.0.0.255
network 192.168.27.0 0.0.0.255
network 10.10.7.0 0.0.0.255
quit
quit
R3
ospf 1 router-id 3.3.3.3
area 0
network 192.168.37.0 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
第三步，本步驟是重點，我們來配置BGP：BGP聯盟與路由反射器
**R1上配置BGP，AS編號爲100**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上配置BGP，AS編號爲64523，聯盟編號200**bgp 64523
router-id 2.2.2.2
confederation id 200
peer 192.168.12.1 as-number 100
peer 10.10.7.7 as-number 64523
peer 10.10.7.7 connect-interface LoopBack0
peer 10.10.7.7 next-hop-local
quit
**R7上配置BGP，AS編號爲64523，聯盟編號200**bgp 64523
router-id 7.7.7.7
confederation id 200
peer 10.10.2.2 as-number 64523
peer 10.10.3.3 as-number 64523
peer 10.10.2.2 reflect-client
peer 10.10.3.3 reflect-client
quit
**R3上配置BGP，AS編號爲64523，聯盟編號200，與64545建立鄰居關係**bgp 64523
router-id 3.3.3.3
confederation id 200
confederation peer-as 64545
peer 10.10.7.7 as-number 64523
peer 10.10.7.7 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上配置BGP，AS編號爲64545，聯盟編號200**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
quit
**R5上配置BGP，AS編號爲64545，聯盟編號200**bgp 64545
router-id 5.5.5.5
confederation id 200
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上配置BGP，AS編號爲600**bgp 600
router-id 6.6.6.6
peer 192.168.56.5 as-number 200
import-route direct
quit
最終測試R1的LoopBack 0與R6的LoopBack 0網絡互通，如下圖：
