#删除旧的路由和网关信息，添加新的网关

ip ro del 10.10.88.0/16
ip ro del 192.168.88.0/24
ip route del default via 192.168.1.111
ip route add default via 192.168.1.1

#删除旧的路由信息，添加新的路由信息
ip ro del 10.10.88.0/16
ip ro del 192.168.88.0/24
/sbin/ip ro add 10.10.88.0/16 via 192.168.1.1
/sbin/ip ro add 192.168.88.0/24 via 192.168.1.1
