設(shè)備是Catalyst8540 CSR 。配置了ISL.VLAN.BVI,并且采用了HSRP協(xié)議。這些例子中是用的是IP地址的保留地址，在擁護(hù)網(wǎng)絡(luò)中使用時(shí)要更換成你們自己想要的合法IP地址。
實(shí)例：
涉及到技術(shù)有: ISL VLAN GEC IRB 技術(shù) ， Cisco 的ISL技術(shù)潤(rùn)許將任何快速以太口配置成中繼端口。生成樹協(xié)議可以在中繼端口上探測(cè)到并打破環(huán)路。
具體情況如下：
快速以太口0/0/0劃分了端口，然后在子端口上封狀了ISL協(xié)議，而快速以太端口0/0/0作為中繼端口，它上面的每個(gè)子端口連接到一個(gè)VLAN。在千兆以太端口上使用了GEC端口綁定技術(shù)和橋接技術(shù)，并在目標(biāo)端口GEC1/0/0上配置了端口探測(cè)。
具體配置單如下：
