前言
本文档介绍了RGNOS V10.3(3)中BGP和OSPF路由重发布时的一些
实现特点。
由于这些特点区别于友商CISCO的BGP功能实现，在具体的项目实
施过程中需要注意。

1. 1OSPF重分发BGP路由
1. 1.1注意点
1. 这里Cisco验证的版本为c7200-adventerprisek9-mz.124-9.T1.bin
2. 1.2应用实例
1. 1.
2.1网络拓扑
四台设备之间建立EBGP/IBGP/EBGP连接。C1为CISCO 3550、C2、
C3是Cisco模拟器，R1是我司设备，实验设备为RG-S5750。C1和
R1建立EBGP连接，R1和C2建立IBGP连接，C2和C3建立EBGP
连接。其中C1和C3主要是发送路由，具体的操作在R1和C2。2. 1.2.2配置文件
