Generally, the router is divided into two types, namely:
1. Static router (router static): is a router that has a static routing table in the settings manually by the network administrator.
2. Dynamic router (router dynamic): is a router that has a routing table and automatically, by listening to the network traffic and also interconnected with other routers.

Coordination of each Router: 
In static routing, the entries in the forwarding routing table is filled and removed manually, whereas the dynamic routing changes are made automatically through a routing protocol. 

Static routing is the simplest routing settings that can be done on a computer network. Using pure static routing in a network means filling every entry in the forwarding table at each router in the network. 

The use of static routing in a small network is not necessarily a problem, just a couple of entries that need to be loaded on the forwarding table in each router. But you can certainly imagine what if must complete forwarding table on each router that number is not small in large networks. 
Especially if you are assigned to fill in the entries in all routers on the Internet are numerous and growing every day. Of fuss once! Dynamic routing is the method used to remove the obligation to fill forwarding table entries manually. 

Routing protocols set up the routers so that they can communicate with each other and give each other routing information that can change the contents of the forwarding table, depending on the state of the network. In this way, routers know the final state of the network and is able to forward the datagram to the right direction. In other words, dynamic routing is the routing of data in the process of filling the routing table automatically. The following table-specific differences in the two types of routing
