A strong understanding of routing principles, including static and dynamic routing, is fundamental for anyone tasked with configuring and managing network traffic.

Routing Table Components

A router uses a routing table to determine the best path for sending data across a network. Understanding the various components of a routing table is essential. Key components include:

• Network Destination: The destination network to which the data is being forwarded.
• Next Hop: The next router or device in the path that will forward the data towards its final destination.
• Metric: The value used by routing protocols to determine the cost of reaching a destination. The metric can be based on factors such as hop count, bandwidth, and delay.
• Administrative Distance: A value that represents the trustworthiness of a routing protocol. It helps determine which routing protocol’s route is preferred when multiple protocols provide routes to the same destination.

Static Routing

Static routing is the process of manually configuring routing paths between routers. Although static routes are simple to configure, they do not adjust automatically to network changes, such as link failures or topology changes. In the CCNA exam, candidates must be able to:

• Configure static routes for IPv4 and IPv6.
• Implement default routes to guide traffic destined for unknown networks.
• Understand the limitations of static routing, particularly in larger or more dynamic networks.

Dynamic Routing Protocols

Dynamic routing protocols automatically discover and maintain routes, adjusting to network changes. Understanding how to configure and troubleshoot the following protocols is critical for CCNA candidates:
