In a scenario where an organization deploys active-active data centers with active-standby firewalls in each data center within a Cisco ACI Multi-Pod environment, maintaining traffic symmetry through firewalls is crucial for consistent security policy enforcement and avoiding asymmetric routing issues. Enabling Pod ID Aware Redirection allows for intelligent redirection of traffic based on pod identification numbers so that return traffic can be directed back through the same path it originated from, thus maintaining symmetry even in complex multi-pod deployments.
