BGP配置实验之路由反射器

发布时间:2015-12-14 09:28

 1、路由反射器解析

 
路由反射器工作原理:
 
RR从EBGP收到的路由,会反射给客户端和非客户端
RR从客户端收到的路由,会反射给客户端、EBGP邻居和非客户端
RR从非客户端收到的路由,只会反射给客户端和EBGP邻居,不会反射给非客户端
 
2、实验拓扑
 
3、基础配置
R1配置
interface Loopback0
 ip address 1.1.1.1 255.255.255.0
interface Serial0/0
 ip address 12.1.1.1 255.255.255.0
router bgp 1
 no synchronization
 bgp router-id 1.1.1.1
 network 1.1.1.0 mask 255.255.255.0
 neighbor 12.1.1.2 remote-as 2
 no auto-summary
 
R2配置
interface Loopback0
 ip address 2.2.2.2 255.255.255.0

 router-id 2.2.2.2
 network 2.2.2.0 0.0.0.255 area 0
 network 23.1.1.0 0.0.0.255 area 0
router bgp 2
 no synchronization
 bgp router-id 2.2.2.2
 neighbor 3.3.3.3 remote-as 2
 neighbor 3.3.3.3 update-source Loopback0
 neighbor 3.3.3.3 next-hop-self
 neighbor 12.1.1.1 remote-as 1
 no auto-summary
 
R3配置
interface Loopback0
 ip address 3.3.3.3 255.255.255.0
interface Serial0/0
 ip address 34.1.1.3 255.255.255.0
interface Serial0/1
 ip address 23.1.1.3 255.255.255.0
router ospf 110
 router-id 3.3.3.3
 network 3.3.3.0 0.0.0.255 area 0
 network 23.1.1.0 0.0.0.255 area 0
 network 34.1.1.0 0.0.0.255 area 0
router bgp 2
 no synchronization
 bgp router-id 3.3.3.3
 neighbor 2.2.2.2 remote-as 2
 neighbor 2.2.2.2 update-source Loopback0
 neighbor 4.4.4.4 remote-as 2
 neighbor 4.4.4.4 update-source Loopback0
 no auto-summary
R4配置  http://www.luyouqiwang.com/
interface Loopback0
 ip address 4.4.4.4 255.255.255.0
interface Serial0/0
 ip address 34.1.1.4 255.255.255.0
router ospf 110
 router-id 4.4.4.4
 network 4.4.4.0 0.0.0.255 area 0
 network 34.1.1.0 0.0.0.255 area 0
router bgp 2
 no synchronization
 bgp router-id 4.4.4.4
 neighbor 3.3.3.3 remote-as 2
 neighbor 3.3.3.3 update-source Loopback0
 no auto-summary
 
4、水平分割导致的问题
 
5、配置路由反射器解决水平分割
R3配置
router bgp 2
 neighbor 2.2.2.2 route-reflector-client
 neighbor 4.4.4.4 route-reflector-client
