Routing is a process in which a router receives a packet from one interface, directs the packet according to its destination address and forwards it to another interface. It is a packet forwarding deviceof network layer which working in the third layer of the OSI reference model --
The structure of IP address has two parts, one part defines the network number, and the other part defines the host number in the network. Communication can only take place between the IP addresses with the same network number. To communicate with the host of other IP subnets, it must go through a router or gateway on the same network. The ip addresses of different network numbers cannot communicate directly, even if they are connected together.
Routing is generally divided into three kinds, static route, dynamic route and direct route. Now introduce static route.
Static routingIs made up ofconservatorInrouterA fixed routing that is manually configured.
Static routing allows for precise control of the behavior and reduced One-way network flow as well as simple configuration.Static routing has the highest priority because of it’s shortest administrative distance. Static routing which is setting a fixed routing table in the router. The static routing will not change unless network administrator intervention . Because static routes cannot reflect network changes, they are generally used in networks with small scale and fixed topology.The advantage of static routing is its simplicity, high efficiency and reliability. Of all the routes, the static routes have the highest priority.When a dynamic route conflicts with a static route, the static route prevails.
On our OLT or ONU, you can configure static routing. For example, the configuration on our olt:
Configure a static route on the olt 
192.168.4.1 is the purpose ip, 255.255.255.0 is the mask, and 192.168.2.6 is the next jump ip address, that is to say, when the destination address of the discovery message is 192.168.4.1, the route will forward the message to 192.168.2.6, to complete the cross-network segment communication.
You can command to view the route later
The general introduction of static routing we mentioned this time is the above content.
