NimbostratusF5 Cluster IP addresses
Im trying to find clear documentation that tells me what requirements / restrictions we have on IP addresses that are required to operate a cluster.
My main question is do the various addresses assigned to support the cluster require being in the same subnet.
The design that we are looking at roughly is
4 Velos appliances (2 in each DC). There will be a tenant on each appliance which will be clustered together. Ideally we prefer not to stretch L2 and operate with L3 as much as possible. So i want to confirm if appliances in DC1 can reside on 1 subnet and appliances in DC2 can reside on another subnet.
Each Tenant would essentially be on a stick / one-arm for data. All traffic would come in and leave on the same interface. The F5 does not directly sit in any of the networks where servers reside. I will be using BGP & RHI to inject routes into the rest of the network to ensure traffic finds the correct active F5.
for example
F5a-DC1-Ten1a = VLAN-HA - 172.28.0.1 and VLAN-Routed - 192.168.250.1
F5b-DC1-Ten1b = VLAN-HA - 172.28.0.2 and VLAN-Routed - 192.168.250.2
F5a-DC2-Ten1a = VLAN-HA - 172.29.0.1 and VLAN-Routed - 192.168.251.1
F5a-DC2-Ten1b = VLAN-HA - 172.29.0.2 and VLAN-Routed - 192.168.251.2
Sorry if I've not made much sense.
