小综合实验：VLAN+STP+HSRP+路由

小综合：VLAN+STP+HSRP+路由

配置思路：

1、分析项目需求
2、项目实施
       -配置终端
            PC： 192.168.10.1/24  ---- 192.168.10.254

             ping x.x.x.x
       -优化
            链路跟踪-上行链路跟踪技术
                VRRP/HSRP 主网关，可以跟踪上行链路的状态，
                如果端口 down ，则会主动降低自己的优先级，
                以确保 备网关，可以立刻升为 主网关。
            #配置：
                interface vlanif 10 
                  vrrp vrid 10 track interface gi0/0/1 reduce 100 ;
3、项目验收
4、项目复盘

企业网络的经典组网架构：
核心层 - 负责全网数据的转发交换
汇聚层 - 是实现网络中的策略配置(可选)
接入层 - 仅仅是作为终端设备的接入；
