最后验证：
可以通过 display vrrp verbose 命令查看配置后的结果。

显示 Switch A 上备份组的详细信息。

[SwitchA] display vrrp verbose

显示 Switch B 上备份组的详细信息。

[SwitchB] display vrrp verbose

显示信息表示在备份组1中Switch A为Master，Switch B为Backup，缺省网关为10.1.1.100/25
的主机通过 Switch A 访问 Internet；备份组 2 中 Switch A 为 Backup，Switch B 为 Master，缺省网
关为 10.1.1.200/25 的主机通过 Switch B 访问 Internet。
