使用GNS3+IOU

richardwei

小弟很奇怪，，求大神解答
使用GNS3的iou来模拟的，file:///C:/Users/Richard/AppData/Roaming/Foxmail7/Temp-6568-20160428081624/Catch(04-28-13-00-37).jpgIOU1,2开启2层etherchannel，vrrp，mstp，dhcp，vtp，IOU3,4开启vtp，端口划分vlan，剩下的模拟PC，从dhcp获取地址
奇怪的是1，IOU5与8属于不通的vlan，有时ping的通有时ping不通，，就连网关也是，，
              2，还有种是谁也ping不通，其他的却能ping通他
拓扑是这样

通过查看你的拓扑 可以看出你几个问题？

1.IOU 5/6/7/8 分别划分到了哪个vlan？
2.你在DS3上已经创建了DHCP 地址池， DS4上就没有必要再配置DHCP?
3.MSTP 配置中 DS3为 主VLAN 25，26 和  DS4 为主VLAN 27,那么对应VRRP的DS3 应该为VLAN 25 26的主路由器，DS4为VLAN 27的主路由器。


配置思路参考：
1.配置汇聚层的链路聚合  先Trunk再划分到隧道.
2.配置汇聚层和接入层的交换机 先配置Trunk 再配置vtp 最后修改生成树协议
3.配置接入层的端口划分 先检查接入层是否获取到与汇聚层一样 的vlan信息，再根据对应端口划分vlan
4.配置DHCP,在汇聚层主交换机上配置就可以了！

这个题难道好大，NA区估计搞不定哦

1、5,6,7,8分别划到那个vlan有关系吗？？随机分的
2、这个可有可无，只是想的若是分配dhcp那台挂了，dhcp不会受到影响啦
3、mstp与vrrp的主也需要对应呀？为什么呢？

参考配置
1.我的汇聚层做了2层的etherchannel的捆绑，我用的gns3模拟的，我尝试过一次3层的聚合，结果引起链路震荡
2，3,4.我是这么做的
