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

Gateway of last resort is not set

C 34.34.34.0 is directly connected, Serial1/0

6、测试 BGP 配置结果，有 R4 开展 PING
