【keepalived】關於keepalived配置中的 mcast_src_ip 和 unicast_src_ip【轉】

keepalived官網解釋

           # 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 <IPADDR>
           unicast_src_ip <IPADDR>

如果兩節點的上聯交換機允許組播，采用組播模式（默認）

mcast_src_ip    發送多播包的地址，如果不設置默認使用綁定網卡的primary ip

 

 

 

 

如果兩節點的上聯交換機禁用了組播，則只能采用vrrp單播通告的方式

unicast_src_ip  xx.xx.xx.xx

unicast_peer {
