S7506E-X vrrp怎么联动ping不同吓一跳地址vrrp的网关失效呀。
两台交换机跑的vrrp,怎么做可以当ping不同下一跳地址时vrrp切到备用网关?有没有典配?用nqa怎么联动呀

本案例适用于如S5120-EI、S5130-EI等的V5交换机,V5、V7交换机具体分类及型号可以参考“1.1 Comware V5、V7平台交换机分类说明”。
SW1、SW2、SW3和SW4连接了2.2.2.0/24和3.3.3.0/24两个网段,在交换机上配置静态路由以实现两个网段的互通,并配置路由备份以提高网络的可靠性。
SW2上配置环回口L0模拟2.2.2.0/24网段内的主机,在SW2上存在两条到达3.3.3.0/24网段的静态路由,下一跳分别为SW1和SW4,这两条静态路由形成备份,其中:
· 下一跳为SW1的静态路由优先级高,作为主路由。该路由可达时,SW2通过SW1将报文转发到3.3.3.0/24网段。
· 下一跳为SW4的静态路作为备份路由。
· 在SW2上通过静态路由、Track与NQA联动,实时判断主路由是否可达。当主路由不可达时,备份路由生效,SW2通过SW4将报文转发到3.3.3.0/24网段。
同样地,SW3上配置环回接口L0模拟3.3.3.0/24网段内的主机,在SW3D上存在两条到达2.2.2.0/24网段的静态路由,下一跳分别为SW1和SW4。这两条静态路由形成备份,其中:
· 下一跳为SW1的静态路由优先级高,作为主路由。该路由可达时,SW3通过SW1将报文转发到2.2.2.0/24网段。
· 下一跳为SW4的静态路作为备份路由。
· 在SW3上通过静态路由、Track与NQA联动,实时判断主路由是否可达。当主路由不可达时,备份路由生效,SW3通过SW4将报文转发到2.2.2.0/24网段。
