说明
ip route add adds new routes to the kernel routing tables. Routes determine how packets are forwarded to their destinations based on the destination address. A route specifies either a gateway (next-hop router) to forward packets to, or an interface for directly connected networks. Multiple routing tables can be used for policy routing.
