2、離；5、 端口聚合，在雙核心之間用若干條線互連，把這些端口加入到聚合端口，打trunk，來(lái)作為Vrrp的心跳線；6、 ACL 訪問(wèn)控制列表 、NAT 網(wǎng)絡(luò)地址轉(zhuǎn)換，設(shè)置在出口路由器中，允許哪些用戶上網(wǎng)，創(chuàng)建NAT地址轉(zhuǎn)換池，允許上網(wǎng)的網(wǎng)段調(diào)入overload即可。接下來(lái)是我在做這個(gè)實(shí)驗(yàn)的過(guò)程：首先是寫好配置模板，寫模板的好處是，理清思路，配置有條理，出了問(wèn)題先看看模板有沒(méi)有問(wèn)題，缺少什么等接入層交換機(jī)的配置模板：conf tspanning-tree spanning-tree mode mstp（開啟多生成樹Mstp）vlan 2vlan 3vlan 4vlan 5vlan 6vlan 7e
