书上说vtp transparent 不支持 vtp pruning,在执行vtp pruning的网络里加入transparent mode的交换机会使网络不稳定,要求在全网关闭pruning 或关闭 transparent switch 下面switch的vlan pruning。
问题:为什么会引起不稳定?
我实验A-B-C, A 是vtp server, B是vtp transparent mode, C是vtp client,在A和C上起SVI,在A 上起vtp pruning,A和C 仍能通信,为什么并没有影响网络?

Hi ZhiWei,
vtp prunning 只是在vtp server/client模式下才起作用。transparent 模式需要手动配置prunning,通过在端口配置allow vlan。在vtp prunning的网络中加入vtp transparent的交换机可能会造成网络问题。按照你的例子sw1 - sw2 - sw3, sw1是vtp server,sw3是vtp client,sw2是vtp transparent,sw1启用vtp prunning。假设sw3上有vlan 1,2,sw2有vlan 1,2,3,sw1有vlan 1,2,3。因为vtp prunning,sw3会告诉vtp server只需要vlan1和vlan2的数据;sw2虽然不参加vtp prunning但是它会转发vtp prunning到sw1,sw1从sw2收到vtp prunning的包。这时候在sw1和sw2之间的 trunk,vlan 3会被pruned。

Will it be possible to convert in English and define what you expect?
