Hi, i´m sorry if this is a classic question.
i have implemented rapid pvst like show in the image. The dotted lines are the alternative links. (image 1)
SwitchA# spanning-tree vlan 1 root primary
SwitchB# spanning-tree vlan 1 root secondary
I want to make a kind of balancing like image 2. But the problem is that i have vlan 100 (and other vlans) in side A and Side B.
So, if i make
SwitchB: spanning-tree vlan 100 root primary
SwitchA: spanning-tree vlan 100 root secondary
The SwB it change to primary for vlan 100.
But i want to the switchB be the primary for side A and secondary for side A. No matter the vlan. Is possible?
Thanks a lot!

PS: Later i will implement HSRP.

Please use odd and even numbering for vlan assignment
Site A - all odd number vlans
Site B - all even number vlans

Hi, i know that is possible, but doing this the result is unbalanced for mi network. For example vlan 20 reside in all switches and vlan 21 reside in only one switch.
i want to the switchA be the primary for side A and secondary for side B. No matter the vlan. Like image 2.
I hope to be clear.
Thanks.
