keepalived官网解释

           # default IP for binding vrrpd is the primary IP
           # on interface. If you want to hide the location of vrrpd,
           # use this IP as src_addr for multicast or unicast vrrp
           # packets. (since it's multicast, vrrpd will get the reply
           # packet no matter what src_addr is used).
           # optional
           mcast_src_ip 
           unicast_src_ip 

如果两节点的上联交换机允许组播，采用组播模式（默认）

mcast_src_ip    发送多播包的地址，如果不设置默认使用绑定网卡的primary ip

 

如果两节点的上联交换机禁用了组播，则只能采用vrrp单播通告的方式

###########################

unicast_src_ip  xx.xx.xx.xx

unicast_peer {

    xx.xx.xx.xx

 }
