multiple subnets within a vlan not allowed?

 

Those subnets are within same vlan and all have the same vlan id 399 on cisco, to break them out to four different vlans on F5, what're the vlan ids need to be on the F5?

 

Or these need to be untagged? Right now, they are created as tagged on both ends and the vlan id on cisco match the one on F5.

 

 

Also, do you mean create four vlan each tie to one physical interface? Then why do we need to do trunk. My understanding of F5 trunk is to aggregate throughput and the aggregated link is suppose to be treated as one single interface.

 

 

Any clarification will be greatly appreciated.

 

 

 

Thanks!!
