How can routes be redistributed between routing protocols?

How can routes be redistributed between routing protocols?

• A. By using static routes
• B. Through configuration of policy or specific commands
• C. Automatically through EIGRP
• D. Via BGP path attributes

Answer: (B)

Redistributing routes between routing protocols involves the use of specific configurations or policies that dictate how routes from one protocol are shared with another. This process enables different routing protocols to understand and utilize the routes learned from each other. In particular, configuring policy or using specific commands provides the necessary mechanisms to control which routes are redistributed, how they are redistributed, and under what conditions. This allows network engineers to fine-tune routing behavior and ensure optimized traffic flow across the network. Static routes, while they can contribute to routing, do not facilitate the dynamic exchange of routes between protocols. Their role is limited to directly defining a path to a destination rather than integrating different routing protocols. EIGRP does offer certain features for routing information exchange but does not automatically redistribute amongst all routing types without proper configuration. BGP path attributes pertain specifically to BGP's operational methods and do not apply to the general redistribution of routes between different routing protocols. Thus, using configuration of policy or specific commands is the correct approach to achieve proper route redistribution, making this method essential for inter-protocol interactions in a multi-protocol environment.
