Can I use Rapid-PVST and RSTP on the same network

[Ethan and Mia]

Hi all

May I have a question 

Our network have more than 20 vlan

Core switch use Rapid-PVST

Access switch user RSTP

Are they can work together ?

thank for advance.

yes, they can exist in the network, you need to look at the model of the switch and IOS have any limitations.

but when Rapid-PVST able to meet the requirement, what is use case to have RSTP (bit old and legacy still required to 30-50 seconds to converge)

you can also look MST if you like, but Rapid is quicker in terms of STP timers and convergence.

That's an "it depends" answer.

I believe it's possible in some cases; don't recall all the specifics.

Probably most likely is if the non rapid-PVST equipment only hosting one VLAN, if it's hosting multiple VLANs, wouldn't expect you to be able to use different links per VLAN (for load sharing purposes) on the non-Cisco equipment.

You could also consider shifting to MST.
