# Checking all the addresses in a received VRRP advert can be time
# consuming. Setting this flag means the check won't be carried out

# Enforce strict VRRP protocol compliance. This will prohibit:
# 0 VIPs
# unicast peers
# IPv6 addresses in VRRP version 2
# 通过ip addr可以看到vip已经顺利挂载，但是无法ping通，并且防火墙都已关闭：
#原因是keepalived.conf配置中默认vrrp_strict 打开了，需要把它注释掉。
# 重启keepalived即可ping通。
vrrp_strict
# The following options can be used if vrrp, checker or bfd processes
# are timing out. This can be seen by a backup vrrp instance becoming
# master even when the master is still running because the master or
# backup system is too busy to process vrrp packets.
# --
# Set the vrrp child process priority (Negative values increase priority)
