BGP-IBGP-EBGP实验配置

好久没看网络的东西，最近突然心血来潮，温习一下BGP的路由协议，虽说这个协议企业里面使用很少，但是总归还是一个重要的协议，以下为GNS3拓扑图，其中R1/R2/R4为C7200，其他的均为3640

R1/R2/R3/R4运行基于OSPF的iBGP协议，R1与R5、R7之间，R4与R6、R8之间运行基于EIGRP的eBGP协议。

注意点如下，在配置里面也做了标注

1、iBGP中运行的IGP协议需要通告所有的loopback接口的IP，否则iBGP邻居无法建立

2、BGP中需要通告相关的接口IP路由，否则bgp路由表中无相关的BGP路由

3、eBGP不需要指定loopback口建立邻居，直接使用物理接口
