VRRP+防火墙双机热备实现企业内网访问互联网
实现的目的：
1.配置完成后，SW1、SW2、SW3开启mstp，SW1为根桥、SW2为备根桥，SW3的g0/0/22端口阻塞，且FW1为主防火墙，FW2为热备防火墙，内网用户通过 SW3-->SW1-->FW1-->互联网；
2.防火墙之间使用Ge1/0/2端口互联，此线路为ha线路，作用是防火墙之间的vrrp心跳线。（在路由器或者交换机开启VRRP时，不需要心跳线）
3.当SW1和SW2、SW3之间任何一条线路断掉，都不会影响业务；
4.当FW1和SW1之间的线路断开后，主防火墙变为FW2，vrrp3和vrrp4的虚拟IP切换到FW2。此时，内网用户通过 SW3-->SW1-->FW2-->互联网
注意：
1.心跳线可以使用多条线路做成链路聚合，本实验仅用一条。
2.SW1、SW2、SW3开启mstp，SW1为根桥、SW2为备根桥，此时SW3的g0/0/22端口阻塞。
3.如果防火墙连接的是运行商的路由器，那就需要配置默认路由 ip route-static 0.0.0.0 0 运行商IP。 本实验连接的是交换机，且PC2的网关在防火墙上，所以不用配置。
此实验中SW4为傻瓜交换机。
