3. Disadvantages of Static Routing
Administrative work is more.
Compulsory need of Destination Network ID’s
Used for only Small organizations
It cannot dynamically update topology changes.

4. Default Routing
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
