  When using this type of protocol network administrator will enter static routes in routing table manually by showing the following features in the routing table; id of the network which contain destination IP address and a subnet mask, IP address for next router and router interface for forwarding packet to the destination.

 Once routing protocol entered into the routing table it will remain unchanged throughout the router’s operation.

Dynamic routing protocol.

  Higgins, & Title (2003) say that this type of protocol have two part, one is routing protocol which is used by adjacent network to pass information about their network environment, second is routing algorithm which determines the shortest path  a packet will takes in the network. Also this type of protocol is used to define method of sharing the information externally while the algorithm is a method of processing information internally.

  On dynamic router, routing tables are updated automatically based on the exchange of routing information with other routers.

 Dynamic routing protocols have two types of protocol mostly used namely; distance vector routing protocol and link state routing protocols.

Distance vector routing protocols

Distance vector routing protocol shows the number of hops to the network destination (the distance)and packet direction to the network destination(the vector).Distance vector algorithm, is also known as the Bellman-ford algorithm, this protocol enables to convey route updates to its adjacent routers at regular scheduled intervals. Each adjacent router adds own distances values and passes the routing information to next router. Distance vector routing protocol uses hop counts as routing metric. This routing metric is used to define the route that router uses to find the best of matching routes in IP routing table while the hop count is the total number of routers that a packet crosses to reach desired destination. Routing information protocol (RIP) is used together with distance vector routing protocol, they are in two versions RIP version 1 and RIP version 2.RIP version 2 provide these functionality; authentication, support of classless networks and announcing of multicast argued by Medhi, & Ramsamy (2007)

Link state routing protocols

Link state routing provides faster convergence than vector routing protocol. Convergence is a way in which router updates routing table when network topology is changed. Changes taken will be replicated to other routers which need to know about changes. This type of protocol requires less bandwidth than distance vector routing protocol. Link state routing protocol offers updates only when the network link states changes. Craig & Roberta (2005) explain that Link state routing protocol in window server 2003 uses routing and access service which support the open shortest path first (OSPF) protocol. OSPF work is to execute complete compiled topological databases of connected network. The shortest path first (SPF) algorithm computes the least –cost path to each destination
