Static Route Explanation with Example

Static Routing:

===========

Static routing is the most secure way of routing. It reduces overhead from network resources. In this type of routing we manually add routes in routing table. It is useful where numbers of route are limited. Like other routing methods static routing also has its pros and cons.

Advantage of static routing

·    It is easy to implement.

·    It is most secure way of routing, since no information is shared with other routers.

·    It puts no overhead on resources such as CPU or memory.

Disadvantage of static routing

·    It is suitable only for small network.

·    If a link fails it cannot reroute the traffic.

For demonstration purpose we will use Packet Tracer network simulator software. Beside Packet Tracer you can use any other network simulator software such RouterSim, GNS, Boson or even better if you could afford, use real Cisco devices for follow this practice.

Create a topology as illustrate in following figure.

Or download this pre created topology.

To Download Packet Tracer File as shown above:

Q. What is the difference between the two methods to create static routes?

A. There are two methods to create static routes:

·       The ip route 10.1.1.1 255.255.255.0 eth 0/0 command generates an ARP broadcast that looks for the next-hop IP address.

·       The ip route 10.1.1.1 255.255.255.0 172.16.1.1 command does not generate an ARP request. It keeps Layer 2 out of the routing process.
