IPRoute路由跟踪

      当服务器有电信、移动双线时，并且都需要直接对外提供服务，服务器需要做路由跟踪。电信用户访问电信线路，并从电信网关返回；移动用户访问移动线路，并从移动网关返回。服务器主动外连，走默认网关。

      可以使用如下脚本进行配置，使用方法为：

     IpRoute editer by K.C   Date:Dec 09 2010 18:15:50
    ./IpRoute.sh [help] driver0:line:lineView:lineGateWay  driver1:line:lineView:lineGateWay
   ./IpRoute.sh [help] �O��0:�路��Q0:�路描述0:�路�W�P0 �O��1:�路��Q1:�路描述1:�路�W�P1

例:�信+移��
./IpRoute.sh eth0:TEL:TELCOME:x.x.x.x eth1:CM:CMCC:x.x.x.x
