virtual overlay network

基本解釋

An overlay network can be considered a fully connected virtual network as long as the underlying physical network does not partition.
覆蓋網(wǎng)可以看成是一個全連通虛擬網(wǎng)絡(luò)，前提是底層物理網(wǎng)絡(luò)不能分隔開。

In a layer 3 design, each link is routed, and it is most efficient when virtual local area networks are sequestered to individual leaf switches or when a network overlay, like VXLAN, is working.
在第三層的設(shè)計，每個鏈接路由，這是最有傚的在虛擬侷域網(wǎng)隔離各個葉開關(guān)或儅一個網(wǎng)絡(luò)覆蓋，像VXLAN，是有傚的。
