MHSRP+IPSLA应用

拓扑：

需求：

vtp模式为transparent,vtp domain为CCIE

创建vlan10,20

交换机互联口配置为IEEE 802.1Q

SW1为VLAN10的root bridge,VLAN20的backup root bridge

SW2为VLAN20的root bridge,VLAN10的backup root bridge

SW1:VLAN10为HSRP组1的Active Router,VLAN20为HSRP组2的Standby Router

SW2:VLAN20为HSRP组2的Active Router,VLAN10为HSRP组1的Standby Router

当ISP1链路失效时，流量切换到ISP2
