keepalived只使用vrrp十分困惑

spike8800

我用两个虚拟机设置vrrp，不使用lvs，只是测试vrrp，但是不管用keepalived
虚拟机一：
! Configuration File for keepalived

global_defs {
   notification_email {
     acassen
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_DEVEL
}


vrrp_instance VI_1 {
    state MASTER
    interface eth4
    garp_master_delay 10
    smtp_alert
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.2.3.154
    }
}这是全部文件，因为我只想试试vrrp功能

虚拟机2：

global_defs {
   notification_email {
     acassen
   }
   notification_email_from Alexandre.Cassen@firewall.loc
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id LVS_DEVEL
}


vrrp_instance VI_1 {
    state BACKUP
    interface eth1
    garp_master_delay 10
    smtp_alert
    virtual_router_id 51
    priority 10
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        10.2.3.154
    }
}这是全部文件，因为我只想试试vrrp功能

使用ip a看 两个机子上都有 inet 10.2.3.154/32 scope global eth*，没有竞争

为什么会出现master发送arp但是backup收不到呢，二者不竞争。
tcpdump backup 信息为：
11:32:10.254780 ARP, Request who-has 10.2.3.154 (Broadcast) tell 10.2.3.154, length 46
11:32:10.254929 ARP, Request who-has 10.2.3.154 (Broadcast) tell 10.2.3.154, length 46

受到了，但是没有回啊

看到master上有多个接口
确认下是否是如此的
