原创
BGP路由反射
提供了在大型I-BGP实现中I-BGP全网状连接问题的一个简单解决方案。
详细介绍RFC1966文档。
实验拓扑:
R1-------R7--------R3
分别用串口连接
配置如下:
R7:
hostname
r7
interface
Loopback0
ip address 116.83.25.1
255.255.255.0
interface
Loopback1
ip address 116.83.26.1
255.255.255.0
!
interface
Ethernet0
no ip
address
!
interface
Serial0
ip address
192.168.54.5 255.255.255.252
encapsulation
ppp
no
fair-queue
!
interface
Serial1
ip address
192.168.54.1 255.255.255.252
encapsulation

router bgp
15210
network
192.168.54.0
neighbor 192.168.54.2
remote-as 15210
neighbor 192.168.54.2
route-reflector-client
配置充当反射客户端的每个邻居.
neighbor 192.168.54.6
remote-as 15210
建立BGP对等体关系
neighbor 192.168.54.6
route-reflector-client
no
auto-summary

R2:
hostname
r2
interface
Loopback0
ip address
10.1.1.1 255.255.255.0
!
Router bgp
15210
bgp
log-neighbor-changes
network 10.1.1.0 mask

mask 255.255.255.0
neighbor 192.168.54.1
remote-as 15210
no

R3:
router bgp
15210
no
synchronization
bgp
log-neighbor-changes
network 192.168.54.0
mask 255.255.255.0

配置过程非常简单,但是非常实用。
这是今天呆着无聊做个实验给大家个参考。
