Migration to Rapid SPT

Hi Group,

in a next few weeks I need to upgrade a network from PVST to Rapid PVST. The design is a traditionell 3 Layer Network Two core switche, 20 distribution and maybe 300 Access Switche

My prefered way to upgrade is to start from the access level...and if all are upgraded (only for a pair distribution switche) I change on the two distri SW. The next step I go to the second access - distribution part...and also start again from access to distri....

and at least when all distri and access switches are upgraded I change the core switches

I don't know if this is the right way....can anyone confirm?

Any help are welcome....

Loading thread data ...

it is 1 way.

FWIW - "traditional" designs for campus depends on when you started and what you learned on.

But if you have to change anyway, now is a good time to see if you can come up with a new design rather than just speed up the old one (unless it is already perfect of course :) )

1 prefer a design that doesnt "need" spanning tree at all.

if you make every access switch a separate subnet and route at distribution / core, then you can let the routing protocol handle convergence.

At that point spanning tree is only there to take care of accidental loops, and isnt involved during topology changes.
