生成樹的工作原理： 生成樹協(xié)議的國際標準是IEEE802.1b。運行生成樹算法的網(wǎng)橋/交換機 在規(guī)定的間隔（默認2秒）內(nèi)通過網(wǎng)橋協(xié)議數(shù)據(jù)單元（BPDU）的組播幀 與其他交換機交換配置信息，其工作的過程如下： ·通過比較網(wǎng)橋優(yōu)先級選取根網(wǎng)橋（給定廣播域內(nèi)只有一個根網(wǎng)橋）。 ·其余的非根網(wǎng)橋只有一個通向根交換機的端口稱為根端口。 ·每個網(wǎng)段只有一個轉(zhuǎn)發(fā)端口。 ·根交換機所有的連接端口均為轉(zhuǎn)發(fā)端口。
