初学者关于ipmp疑惑，请大侠指点一二

lg700587

我是在虚拟机中Solaris配置的ipmp，下面是我的配置文件信息：我配的是227是浮动ip，可当我手动把e1000g0 down掉后，227还是在e1000g0上，再把e1000g1 down掉，227还能通，这正常么？2个网卡都down掉了，浮动ip怎么通的？

有网关么？

yuhuohu

自己ping自己死活都是通的吧，你拔插网线还通的话才不正常

    我就是不懂我两个网卡全down掉了，227的地址还能通，我觉得e1000g0如果down掉的话，227这个地址应该跑到e1000g1上，可他没有

    没设网关

    你这是Probe-based的IPMP，应该是通过ping网关来判断网卡是否正常的吧，不设网关自然无法进行切换

    我把网络配置好了，也有网关，同一网段的，但还是不行，down掉e1000g0，227的ip照样还挂在e1000g0的网卡上，怎么回事啊？

    您是说host的？host是浮动IP，是用来切换的啊，本地网卡上的ip应该不用于切换啊。
