奇怪的网络问题，在线求助！

Question

M8000小机，solaris10系统，四个网络接口，分成两组，想把每组做成ipmp冗余，系统信息如下：

bash-3.00#

其中，我是为了做式样，将主机与网关的网络断开的，也就是说网关172.16.1.254不再这个测试网络中，

网络中的另外一台主机racdb3的一个地址是172.16.1.197，

测试时候，从racdb3向172.16.1.206、172.16.1.208 ping的时候是没有问题的，但是racdb4这台主机向racdb2的地址172.16.1.197 ping的时候却有问题：

bash-3.00# ping -s  172.16.1.197        
PING 172.16.1.197: 56 data bytes
ICMP Host Unreachable from gateway 192.168.254.3
for icmp from 192.168.254.3 to 172.16.1.197
ICMP Host Unreachable from gateway 192.168.254.3
for icmp from 192.168.254.3 to 172.16.1.197
ICMP Host Unreachable from gateway 192.168.254.3

^C
----172.16.1.197 PING Statistics----
3 packets transmitted, 0 packets received, 100% packet loss
bash-3.00#

这个信息很明显，就是这台主机向外ping的时候走的是192.168.254.3这个网关，可是这个地址是小机console管理地址，为什么会出现这种现象？

Answer 1

两个默认网关是不可能的
只能一个默认网关,其他需要的路由用route add 加

Answer 2

route add default ip_address
route add 10.0.0.0 10.0.0.10

Answer 3

解决了，就是网关问题，将defaultrout设置一个在网内的网关，一切ok，

但是，我设置了172.16.1.192网段的网关，对于10.0.0.0网段的不起作用，那么solaris如何设着两个不同的网关呢？
