Types of Routing

Routing can be classified into three categories:

• Static Routing
• Default Routing
• Dynamic Routing

Static Routing

Nonadaptive Routing is another name for static routing. It’s a method in which a routing table’s routes are manually added by the administrator. The packets for the destination can be sent via the route set by the administrator by a Router. Routing decisions are not made in this method based on the state or topology of the networks.

Advantages Of Static Routing

• It has no overhead when it comes to the router’s CPU consumption. As a result, the less expensive router can be utilised to achieve static routing.
• Bandwidth: Between the routers, there is no bandwidth utilization.
• It provides security because the system administrator is only permitted to regulate the routing to a certain network.

Disadvantages of Static Routing:

• It becomes extremely difficult to manually add each route to the routing database in a large network.
• Because he must manually add each route, the system administrator should have a thorough understanding of topology.

Default Routing

Default Routing is a strategy in which a router is set up to transmit all packets to the same hop device, regardless of whether it is part of a certain network. A packet is sent to the device for which default routing has been defined. When networks deal with a single exit point, default routing is employed. It’s also helpful when a large number of transmission networks must send data to the same HP device. When a specific route is specified in the routing table, the router will take that route instead of the default. When a specific route is not indicated in the routing table, the default route is chosen.

Dynamic Routing

It’s a routing approach in which a router adds a new route to the routing table for each packet in response to changes in the network’s condition or topology. Adaptive Routing is another name for it. To find novel ways to get to the goal, dynamic protocols are used.

The protocols RIP and OSPF are used to discover new routes in Dynamic Routing.

If any route fails, an automatic modification will be performed to get you to your destination.

In order to exchange routes, all routers must use the same dynamic routing protocol.

When a router detects a change in the condition or topology, it broadcasts the information to all other routers.

Advantages of Dynamic Routing:

• It’s a lot easier to set up.
• It is more successful at determining the appropriate path in response to changing conditions or topography.

 

Disadvantages of Dynamic Routing:

• In terms of CPU and bandwidth utilization, it is more expensive.
• When compared to default and static routing, it is less secure.
