在介面上啟動沒有 IP 的 keepalived？

我想在一個介面上使用keepalived，它會在某個時候獲得一個IP，但最初不會有一個，我可以在配置中以某種方式設置它嗎？如果我現在嘗試啟動它，keepalived 會出錯，因為 keepalived 不知道在發送 VRRP 數據包時要使用哪個源 IP 地址。會議：

！keepalived的配置文件

vrrp_instance VI_1 {
   state MASTER
   interface eth0
   virtual_router_id 51
   priority 150
   advert_int 1
   authentication {
       auth_type PASS
       auth_pass pwd
   }
   virtual_ipaddress {
      192.168.0.13
   }
   notify /etc/state_change.py
}

日誌：

今天發布了新版本的keepalived 2.0.5，它支持尚不存在的介面。FAULT碰巧這也解決了我的問題，因為如果介面沒有 IP，keepalived 將在一個狀態下啟動，這很好。只需添加dynamic_interfaces即可global_defs。

為什麼不使用 ifconfig 給它一個臨時地址呢？
