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，另一条链路将以生厂数据为主。
