[Switchl] ip route-static 0.0.0.0 0.0.0.0 172.16.30.2 preference 70
[Router] ip route-static( 10 )//默认优先级
[Router] ip route-static 192.168.10.0 255.255.255.0 172.16.10.1
[Router] ip route-static 192.168.10.0 255.255.255.0 172.16.20.1 preference70
[Router] ip route-static 192.168.20.0 255.255.255.0 172.16.10.1
