[问题求助]关于bond的问题，bond之后为什么网关找不到，请多多帮助！ [复制链接]

在red hat en.terprise .advance server 下做了双网卡的bond    外汇
按照精华贴子里的步骤。
我的路由表如下：

现在问题如下：
1。为什么我将两个网卡bond之后，网关就找不到了，在/etc/sysconfig/.network-s.cript/ifcfg-bond0 中网关是有的服务器
在/etc/sysconfig/network 中网关也加.了，但是就出不了子网，苦闷.呀！！！            杀毒

2。做好bond之后.，怎么判断是否起了作用，是不是拔掉一.根网线之后，ping 包隔一个出现一次，现在总感觉，我的只是一块网卡起作用？             汽车

各.位老.大，帮帮小弟吧，本以为做好了，现在除了本网段，别的都不能访问，郁闷呀！(广告)

按照精华贴子里的步骤。
我的路由表如下：
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface..........


route add default gw xx.xx.xx.xx bond0加在启动脚本里面
bond应该有4种模式：
mode
        Specifies one of four bonding policies. The default is round-robin.
        Possible values are:

        0       Round-robin policy: Transmit in a sequential order from the
                first available slave through the last. This mode provides
                load balancing and fault tolerance.

        1       Active-backup policy: Only one slave in the bond is active. A
                different slave becomes active if, and only if, the active slave
                fails. The bond's MAC address is externally visible on only
                one port (network adapter) to avoid confusing the switch.
                This mode provides fault tolerance.


        2       XOR policy: Transmit based on [(source MAC address XOR'd with
                destination MAC address) modula slave count]. This selects the
                same slave for each destination MAC address. This mode provides
                load balancing and fault tolerance.

        3       Broadcast policy: transmits everything on all slave interfaces.
                This mode provides fault tolerance.



pls read /usr/src/linux/Documentation/networking/bonding.txt to get further info.

十分感谢这位老兄，我先去看看！
