keepalived virtual_ipaddress 和网络掩码

我有以下 keepalived.conf 文件：

vrrp_script chk_nginx {
  script "curl http://localhost/vrrp_healthcheck/"
  interval 2 # every 2 seconds
  weight 2 # add 2 points if OK
}

vrrp_instance VI_1 {
  interface ens160 # interface to monitor
  virtual_router_id 50
  priority 100
  virtual_ipaddress {
    192.168.120.25 label ens160:10
  }
  track_script {
    chk_nginx
  }
  notify /usr/local/bin/notify.sh
}

在主节点上，我在 ifconfig 输出中看到以下内容：

ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.120.20  netmask 255.255.255.224  broadcast 192.168.120.31

        inet 192.168.120.25  netmask 255.255.255.255  broadcast 0.0.0.0
        ether 00:50:56:a5:c5:3a  txqueuelen 1000  (Ethernet)

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0

        RX packets 9730  bytes 812897 (793.8 KiB)

        TX packets 9730  bytes 812897 (793.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

让我担心的是 ens160:10 条目（由 keepalived 创建的）中不同的广播和网络地址。

这些不应该与常规界面中的匹配吗？

目前，我的设置似乎有效，但我想确保它设置正确。
