• Administrative work is more.

• Compulsory need of Destination Network ID’s

• Used for only Small organizations

• It cannot dynamically update topology changes.

Disadvantages of Static Routing

3

• A Default routing protocol is configured for

unknown destinations.

• Generally used in the internet where the destinations

are unknown.

Example : The address of yahoo is unknown.

• Configured at end points

• It is the last preferred routing

Default Routing
