I'm currently learning about routed networks and have a lab that is implementing a 3 tier leaf spine and have a question. I know that I can create a subnet from which FIP gateway IP addresses are consumed, e.g., openstack subnet create demo-floating-ip-agent-gateway-subnet \ --subnet-range 198.51.100.0/24 --no-dhcp \ --service-type 'network:floatingip_agent_gateway' \ --network demo-ext-net In videos from past OpenStack summits such as this https://youtu.be/XnXSwCSHc4U drawings show that the subnet is used within a single segment's compute nodes, and I can believe that would work. What isn't clear is whether the same subnet should be used across multiple segments, or the intent is for each segment defined in the routed network to have a unique subnet from which these FIP gateway IPs are assigned, e.g., some other segment would be using, say 198.52.100.0/24. In the non-routed network setup where I leanred about DVR it was pretty clear only one subnet was allowed, but what is the best practice/intent for routed nets? Thanks. syd
