Static Routing Advantages and Disadvantages
Static routing advantages:
- Minimal CPU processing.
- Easier for administrator to understand.
- Easy to configure.
Static routing disadvantages:
- Configuration and maintenance is time-consuming.
- Configuration is error-prone, especially in large networks.
- Administrator intervention is required to maintain changing route information.
- Does not scale well with growing networks; maintenance becomes cumbersome.
- Requires complete knowledge of the whole network for proper implementation.
Dynamic Routing Advantages and Disadvantages
Dynamic routing advantages:
- Administrator has less work maintaining the configuration when adding or deleting networks.
- Protocols automatically react to the topology changes.
- Configuration is less error-prone.
- More scalable, growing the network usually does not present a problem.
Dynamic routing disadvantages:
- Router resources are used (CPU cycles, memory and link bandwidth).
- More administrator knowledge is required for configuration, verification, and troubleshooting.
