Now: SW02 currently running OSPF area 0 with redistribute connected subnets which includes VLAN10 with another router/switches which isn't in the picture and not in the scope of this question; VLAN10 contain 10.0.0.1 as gateway for Desktop Group 1 and 2
Objective: We wanted to move Desktop group 2 to site B, since we want IP routing handle individually on site B, which is SW04, we are planning to put 10.0.0.2 as VLAN10 interface IP and that make it become the gateway for Desktop group 2 user in site B, while SW02 and SW04 is running OSPF area 0.
Question: we tested to distribute 10.0.0.0/24 in area 0 between SW02 and SW04, but it seems only being able to handle one subnet with one site only, is there a limitation for route injection not to have same subnet between two sites?
FYI, please don't ask me why it needs to be like this or could it completely change the design, I don't make the rule, that's the business requirement, thanks.
