The role of backhaul routing Why do I need backhaul routing?

In the absence of dynamic routing such as OSPF

A->b, a must know how to get to B so there should be a route for B on a.

When A's packet arrives b,b needs to respond, so B should know how to get to a. Therefore, a route must be reached on B.

Next hop

The next point of the route. if the router is not directly connected to the destination network, it will have a neighbor router that provides the next hop route, which is used to pass the data to the destination.

Used in a routing static configuration. The full syntax is IP route network-address subnet-mask ip-address. Network-address: The destination network address of the remote network to which the routing table is to be joined; Subnet-mask: Subnet mask of the remote network to which the routing table is joined: ip-address: generally refers to the IP address of the next-hop router.
