Hi Team,

We're looking to optimize our OVN deployment in our CLOS network
architecture and would like to get the community's input on moving gateway
chassis placement from leaf to border switches.

Current Architecture:

[Hypervisors] -> [Leaf Switches + OVN GW Chassis] -> [Spine] -> [Super
Spine] -> [Border] -> [PE]


Proposed Architecture:

[Hypervisors] -> [Leaf Switches] -> [Spine] -> [Super Spine] -> [Border +
OVN GW Chassis] -> [PE]


Key drivers for this change:

Optimize external load balancer integration

Improve NAT gateway functionality

Centralize external connectivity management

Better scale for north-south traffic


We'd appreciate insights on:

Performance implications

Best practices for migration

Similar experiences from other deployments

Potential challenges to consider

Has anyone else implemented similar architecture changes? What were your
learnings?

Looking forward to the community's thoughts and experiences.


Best regards,

Srini
