Concepts covered in this module include:
- Using a methodology for troubleshooting Layer 3 problems is important to
isolate and identify the problem as quickly as possible.
- In most networks static routes are used in combination with dynamic routing
protocols. Improper configuration of static routes can lead to less than
optimal routing and in some cases create routing loops or parts of the network
to become unreachable.
- Troubleshooting dynamic routing protocols requires a thorough understanding
of how the specific routing protocol functions. Some problems are common to all
routing protocols while other problems are particular to the individual routing
protocol.
- Troubleshooting redistribution between routing protocols requires an
understanding of how the particular routing protocols function and how to
redistribute their different metrics.
