Feature Overview 

Customer deployment may want to have multiple external gateway devices for the same neutron router. This may falls under two use cases

• Redundancy or HA for external gw routes
• Use of different external network / gw for different type of traffic (storage, inernal API, tenant traffic)

Goals

• Ability to configure and deploy a neutron router to multiple external gw mapping, with ECMP or without
• Provide redundancy for external connectivity
• Different routing paths for different external network type

Requirements 

Done - Acceptance Criteria 

• Functional operation & validation
• ECMP operation with failure detection and failover
• Baseline failover and failure detection time
• Regression and Automation, CI framework support

Use Cases

• Failover to functional external gw upon failure
• Loadbalancing of traffic across the multiple external gw for higher aggregate capacity

Documentation Considerations 

• Feature description, configuration workflow, limitations in Users Guide
• Release notes for new feature

Background and Strategic Fit 

• Explicit customer request for the feature as tactical

• Improve customer adoption and increase market share
