                                            VRRP冗余 RIP/OSPF  STP配置

      VRRP冗余 RIP/OSPF  STP配置


分析:查看sw1 和sw2 的stp可知 sw1和sw2 是根网桥 sw3和sw6的11端口


        为阻塞端口 ,因此可以知道pc机之间数据包的走向,也可以改变交换


        机的角色:stp priority{id}  (为4096的倍数,默认值32768)

==========================================================================

此时外网也可以ping通内网,在现实环境中是不可能存在的,因此外网会运用隔离vlan技术

----------------------------------------------------------------------------------------------------------------------------

        重点:


2层


     链路捆绑


3层

     vlan间路


        路由器


        单臂路由


        SVI


     单点故障


        冗余链路/设备


           链路捆绑(链路备份/数据负载均衡)


              不捆绑(链路备份-浮动路由)


          网关冗余技术

              VRRP(group)

              HSRP

              GLBP

==========================================

确保终端设备(pc/server)互通

     一个网段


           交换


     不同网段


           路由


  故障:


     1.本身的交换故障


     2.单点故障


           冗余链路/设备


                 问题-2层环路问题


                       生成树协议


                 带宽不足的问题


                       链路捆绑


     3.本身路由故障


     4.单点故障


           冗余链路/设备


                 问题-3层环路问题


                       路由协议


                 选路问题


                       路由协议


                 带宽不足问题
