Overview
Explains the purpose of symmetric routing and why it is required to ensure consistent traffic flow, predictable forwarding behavior, and proper stateful inspection in Cisco Catalyst SD-WAN deployments
Feature history for symmetric routing
Lists the development milestones and release information for symmetric routing, including feature description.
Symmetric routing mechanisms for Cisco SD-WAN
Explains symmetric routing and its importance for bidirectional services like NAT and Firewalls.
Translating OMP metrics for devices outside of the overlay network
Describes how transport gateways extend symmetric routing to external LAN devices by translating RIB metrics into BGP or OSPF parameters.
Symmetric routing scenarios
Use these scenarios to understand how transport gateway and Multi-Region Fabric deployments maintain symmetric routing through route re-origination and path-preference attributes across complex, multi-hop topologies and data centers.
Configure symmetric routing
Follow these procedures to implement symmetric routing on your devices.
Verify symmetric routing
Use these verification commands to confirm that your symmetric routing configuration is operating as intended.
Monitor RIB metric translation
Explains how to monitor the translation of OMP metrics into service-side routing protocols.
