By quickly adapting to network topology changes, IGPs contribute to network resilience by rerouting traffic when a link or node fails. On the other hand, BGP governs how networks interact with each other on the internet. This adaptability minimizes downtime and service disruption, thereby reducing the need for 100% redundancy.
