root port：根端口，非根桥上到根桥最近的端口，最近的意思是开销最小；designated port:指定端口，是在每一个物理网段的不同端口之间选举出一个指定端口。“指定端口”与前面所说的“根端口”相对，它可以理解为离下游设备最近的端口，是本物理网段（这里的“网段”是指一个交换机端口所连接的所有设备...
Root Port:到达Root Bridge的最短路径的出发端口。Designated Bridge:对于一个LAN而言，通往Root Bridge最短路径上的所经由的第一个Bridge。如果两个Bridge有相同长度的最短路径，那么取Bridge ID较小的那一个。
The root bridge, root port, and designated port are selected based on the BPDU priority vector {root BID, root path cost, sender BID, port ID}. Devices determine these by exchanging and comparing the values of the fields in the BPDU priority vector. A BID consists of a bridge priority, ...
