出錯原因：
檢查以後發現，en0（192.168.8.230）默認網關是10.10.10.1，所以造成無法通信。進一步檢查發現主機設有多個默認網關。AIX中配置了多條的默認網關，會造成網絡不穩定(例如時斷時好)。
解決方法：
1、查看當前默認網關
如果用route命令（或smitty route)去刪除，下次重啓後，又會回來；所以要從ODM裏刪除。

2、查看ODM信息

標紅的爲多餘網關。
3、逐條刪除沒用的默認路由
[root@aix230:/]#chdev -l inet0 -a delroute="net,-hopcount,2,,0,10.10.10.1"
inet0 changed
4、確認生效
[root@aix230:/]#odmget -q "name=inet0" CuAt
CuAt:
name = "inet0"
attribute = "hostname"
value = "aix230"
type = "R"
generic = "DU"
rep = "s"
nls_index = 24
CuAt:
name = "inet0"
attribute = "route"
value = "net,-hopcount,0,,0,192.168.8.1"
