We have a network of about 35 edge switches with 2 6500 aggregation switches.
Each edge switch connects to both agg switches at layer2.
We have about 250 vlans, and any vlan could be on any switch.
We are intending to move to MSTP but I seem to have a conceptual problem.
I understand that switches must agree about vlan to MSTI mapping.
I do not currently need the load balancing, so was planning an single instance.
Do I actually need ALL vlans to exist on ALL switches though.
ie if I do not need a vlan on a switch can I prune it, or will that make MSTP break?
Having to have all vlans on all switches is an admin nightmare.
