Static Routing in Computer Networks

What is Static Routing?

• A type of routing where the routing table is manually configured and remains static until changed by the network administrator.
• Static routes are defined by the administrator and are not learned through a routing protocol.

Characteristics of Static Routing

• Manual configuration: Static routes are configured manually by the administrator.
• No routing protocol: Static routes do not rely on a routing protocol to learn about the network.
• No automatic updates: Static routes do not update automatically when the network changes.
• No scalability: Static routing is not suitable for large networks due to the manual configuration requirement.

Types of Static Routes

• Default route: A route that is used when no other route matches the destination IP address.
• Host route: A route that specifies a specific host or IP address.
• Network route: A route that specifies a specific network or subnet.

Advantages of Static Routing

• Security: Static routes can be used to restrict access to specific networks or hosts.
• Simple configuration: Static routes are easy to configure and understand.
• No protocol overhead: Static routes do not require the overhead of a routing protocol.

Disadvantages of Static Routing

• Manual configuration: Static routes require manual configuration, which can be time-consuming and prone to errors.
• No automatic updates: Static routes do not update automatically when the network changes.
• Limited scalability: Static routing is not suitable for large networks due to the manual configuration requirement.

When to Use Static Routing

• Small networks: Static routing is suitable for small networks with a simple topology.
• Security-critical networks: Static routing can be used to restrict access to specific networks or hosts.
• Networks with few changes: Static routing is suitable for networks that do not change frequently.
