1、双出口,负载平衡,互备份方案(需使用NAT)说明:内部网络分别有两条专线接入(telecnc)内部网络有vlan2vlan3两个vlan要求vlan2的用户默认走tele,当tele出口中断后自动切换到cnc出口。反之依然。使用技术:HSRPNAT注意:此技术在使用例:“standbyxxtrackf0/070”时只要f0/0接口有任何异常(端口down或者协议down)standby均会自动切换到另一条线路.除非端口down,如果协议down的情况下需要等待端口的keepalive检测出来协议才会down
2、.(默认keepalive是10sencond)但是如果将端口的keepalive时间调整过短,如果线路不稳定,就会引起端口抖动.如果keepalive时间过长.当线路外界dowm掉后,需要等很长时间才能发现协议down.(即keepalive的检测周期)*实际操作中如果是专线接入,从运营商的设备到本地设备可能通过了很多交换设备.所以即使某一段链路down了.本地也有可能检测不出来,即端口和协议仍然是up.拓扑如下:配置如下:Tele:tele#shrunBuildingconfiguration...Cu
