Juniper防火墻HA配置詳解_雙主(L2透明模式)(精)

1、Juniper HA 雙主（L2 透明模式配置實際環(huán)境中防火墻做雙主是不太可能實現(xiàn)全互聯(lián)結(jié)構(gòu)，juniper 防火墻標配都 是4 個物理以太網(wǎng)端口，全互聯(lián)架構(gòu)需要防火墻增加額外的以太網(wǎng)接口（這樣會增加用戶成本，或者在物理接口上使用子接口（這樣配置的復(fù)雜性增加許多，最主要的是 用戶的網(wǎng)絡(luò)中大多沒有像全互聯(lián)模式那樣多的設(shè)備。因此雙主多數(shù)實現(xiàn)在相對冗余的網(wǎng)絡(luò)環(huán)境中。圖中服務(wù)器交換機與核心交換機間采用 OSPF 動態(tài)路由器協(xié)議, 自動完成雙鏈路的流量負載均衡。具體實際環(huán)境如下：FW-A FW-B 核心-1 核心-2 E1/1E1/1E1/4E1/4HAZone: v1-U ntrustZone: v1
