什么是VTP?& [8 n ?# j. K0 }( u
VTP是VLAN Trunk Protocol的简写,它供给每个设备 (router 或 LAN-switch)在中继端口(trunk ports)发送广播. 这些广播被发送到一个组播地址,并被所有相邻设备领受. 这些广播列出了发送设备的打点域,它的设置装备摆设修订号,已知的VLAN, 及已知VLAN简直定参数.经由过程听这些广播,在不异打点域的所有设备都可以进修到在发送设备上设置装备摆设的新的VLAN.使用这种方*,新的 VLAN只需要在打点域内的一台设备上成立和设置装备摆设.信息会自动被不异打点域内的其它设备学到.3 }$ g6 C2 z; ]# H- p
