Route Domains
- Mar 26, 2026
We have used route domains for many customers at an MSP that I worked for and it always ended up being more of an issue for the customer in the long run. I recommend against using route domains if you can avoid it.
Route domains depend upon on your use-case and need. I would avoid route leaking in route-domains, that kind of defeats the purpose of isolating the routing. A route domain should be used to essentially carve a non-vCMP capable BIG-IP and forcing usage on specific gateways/network links and creating a separate failover traffic-group. Route domains are just like a VRF. IMO I don't see value using it for GTM. I used it exclusively in a Trading environment to separate Internet traffic from Colo Traffic within a BIG-IP and it performed flawlessly.
