I am a little confused with assigning ip to computers. I have a topology like this :
Should all segments between Router 9 and Router 10 be on the same subnet ? I should be able to communicate between vlans, so I have to create sub-interfaces on Router 9, but to do this, I have non-overlapping ip for each vlan. If vlans should be on different subnets, what with these two segments with VLAN 30 ?
I am confident, that it might be basic question, but I don't have much experience. Could someone give me any hint ? What is the good way to address it ?
