BGP
实验学时:2
学时 一、实验目的 掌握路由协议的原理;掌握 BGP 协议的工作原理;掌握 BGP 协议的基本配置方法;
二、实验环境(软件、硬件及条件) 3Windows 主机+4 台路由器 或者 1 台 Windows 主机+packet tracer 6.0 模拟器
三、实验内容 理解 BGP 协议的工作原理,并通过 BGP 路由协议实现不同网络互通。
四、实验拓扑
实验中各个网段与路由器接口 IP 地址分配如上图所示(图中,Loopback 接口也 可以用 PC 机替换)
五、实验步骤
1、配置路由器各个接口的 IP 地址等参数,R4 接口状态如下:
2、在 AS100 中配置 IGP 协议 EIGRP,R1 上的配置如下(R2 类似,R2 的 s0/2/1 接口不应该在 EIGRP 中发布):
router eigrp 1
network 12.12.12.0 0.0.0.255
network 1.1.1.1 0.0.0.0
auto-summary
配置完成后 R1 的路由表如下:
R1#show ip rou
Gateway of last resort is not set
1.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 1.0.0.0/8 is a summary, 00:38:19, Null0
C 1.1.1.1/32 is directly connected, Loopback0
D 2.0.0.0/8 [90/20640000] via 12.12.12.2, 00:37:17, Serial1/0
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 12.0.0.0/8 is a summary, 00:38:19, Null0
C 12.12.12.0/24 is directly connected, Serial1/0
3、在 R3 中配置 BGP 协议(R2 类似)
router bgp 300
bgp log-neighbor-changes
no synchronization
neighbor 23.23.23.1 remote-as 100
neighbor 34.34.34.2 remote-as 200
4、在 R4 中配置 BGP 协议
router bgp 200
bgp log-neighbor-changes
no synchronization
neighbor 34.34.34.1 remote-as 300
network 4.4.1.0 mask 255.255.255.0
network 4.4.2.0 mask 255.255.255.0
network 4.4.3.0 mask 255.255.255.0
5、配置完成,查看 R2 的路由表
R2#show ip rou
