摘　　要：文章基于网关负载均衡协议(GLBP)和策略路由(PBR)对某校园网进行改造,以满足校园网用户的需求。新增2条互联网运行商出口链路,既增加校园网出口带宽,又使校园网出口链路多元化;在校园网核心层中部署2台高性能思科7206路由器,并在两者之间运行网关负载均衡协议,既实现校园网三层网关备份又实现流量负载均衡;在核心层2台思科7206路由器子接口处部署策略路由。测试结果表明,此次网络改造不仅实现了三层网关冗余与流量负载均衡,而且使校园网用户访问互联网资源的数据包,能够按照网络管理者预先制定的最优路径策略进行转发。This paper reconstructs a campus network based on GLBP and PBR to meet the needs of campus network users.Two new Internet operator export links are added,which not only increase the campus network exit bandwidth,but also diversify the campus network exit link.Two high performance Cisco 7206 routers are deployed in the campus network core layer and the gateway load balancing protocol works between them.The test results show that the network transformation not only realizes the redundancy of the three-tier gateway and the balance of the traffic load,but also enables the campus network users to access the packets of Internet resources,which can be forwarded according to the optimal path strategy formulated by the network manager in advance.

关 键 词：网关负载均衡协议 策略路由 端口多路复用 单臂路由
