双WAN链路采用offsetlist做链路负载均衡.docx

1、双WAN链路采用offsetlist做链路负载均衡双WAN链路采用offset-list做链路负载均衡本网络采用双WAN链路连接,生厂网络数据通过生厂链路发送,OA网络数据通过OA链路发送,当一条链路失效情况所有数据切换到第二条链路,对生厂网络数据进行QOS优化,生厂网络与OA网络不能进行通迅以下为配置清单:采用EIGRP + offset-list + HSRP 进行冗余备份以下为配置清单,但没有加入ACL与QOS部份的配置。ACL可在交换机上启用，QOS在路由器上启用。启用QOS时注意两条链路的数据优先级（正常情况下，生厂链路以生厂数据为主，OA链路以OA数据以主，不管哪条链路出现问题，另
