HNREL04-BP03 Use dynamic routing for automatic failover

Implement dynamically routing for dedicated connections and IPSec VPN connections using BGP to enable automatic load balancing and failover across redundant links.

Desired outcome: Ensure seamless failover and traffic distribution across all available network paths, minimizing downtime and manual intervention.

Level of risk exposed if this best practice is not established: High

Benefits of establishing this best practice:

  • Enables automatic failover in the event of a connection failure

  • Balances network traffic for optimal performance

  • Reduces manual intervention and operational overhead

  • Increases resilience of hybrid connectivity

Implementation guidance

  • Use BGP for dynamic routing between on-premises and cloud networks.

  • Regularly validate routing and failover with controlled tests.
