BGP 路由联盟、反射器配置命令

首先配置路由接口的IP地址，及每个路由创建一个 LoopBack 接口并配置IP 地址：
R1：
sys
sys R1
int LoopBack 0
ip add 10.10.1.1 24
quit
int g0/0/0
ip add 192.168.12.1 24
quit

R2:
sys
sys R2
int LoopBack 0
ip add 10.10.2.2 24
quit
int g0/0/1
ip add 192.168.12.2 24
int g0/0/0
ip add 192.168.23.2 24
quit

R3:
sys
sys R3
int LoopBack 0
ip add 10.10.3.3 24
quit
int g0/0/1
ip add 192.168.23.1 24
int g0/0/0
ip add 192.168.34.1 24
quit

R4:
sys
sys R4
int LoopBack 0
ip add 10.10.4.4 24
quit
int g0/0/1
ip add 192.168.34.2 24
int g0/0/0
ip add 192.168.45.2 24
quit

R5:
sys
sys R5
int LoopBack 0
ip add 10.10.5.5 24
quit
int g0/0/1
ip add 192.168.45.1 24
int g0/0/0
ip add 192.168.56.1 24
quit
R6：
sys
sys R6
int LoopBack 0
ip add 10.10.6.6 24
quit
int g0/0/0
ip add 192.168.56.2 24
quit

在R2、R3、R4、R5上配置OSPF：
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

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

R4：
ospf 1 router-id 4.4.4.4
area 0
network 192.168.34.0 0.0.0.255
network 192.168.45.0 0.0.0.255
network 10.10.4.0 0.0.0.255

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

每一个路由上配置BGP：
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

R2 :
bgp 64523
router-id 2.2.2.2
confederation id 200
confederation peer-as 64545
peer 192.168.12.1 as-number 100
peer 10.10.3.3 as-number 64523
peer 10.10.3.3 connect-interface LoopBack 0
peer 10.10.3.3 next-hop-local

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 LoopBack 0
peer 10.10.4.4 as-number 64523
peer 10.10.4.4 connect-interface LoopBack 0

R4 :
bgp 64523
router-id 4.4.4.4
confederation id 200
confederation peer-as 64545
peer 10.10.3.3 as-number 64523
peer 10.10.3.3 connect-interface LoopBack 0
peer 10.10.3.3 next-hop-local
peer 10.10.5.5 as-number 64545
peer 10.10.5.5 connect-interface LoopBack 0
peer 10.10.3.3 ebgp-max-hop

R5 :
bgp 64545
router-id 5.5.5.5
confederation id 200
confederation peer-as 64523
peer 192.168.56.2 as-number 600
peer 10.10.4.4 as-number 64523
peer 10.10.4.4 connect-interface LoopBack 0
peer 10.10.4.4 ebgp-max-hop

R6 :
bgp 600
router-id 6.6.6.6
peer 192.168.56.1 as-number 200
network 10.10.6.0 255.255.255.0

在R3路由器上配置反射器：
bgp 64523
peer 10.10.2.2 reflect-client
peer 10.10.4.4 reflect-client
