MSTP and HP Procurve Network
I have a question. Is there any reason that MSTP would need to be configured over standard STP on a heterogeneous and flat HP procurve switched network with a couple of stray cisco access layer switches?

This solution is only available to members.

On a HP Procurve set a root switch with low priority (fx. 0) and a backup root fx. =1.
The default is 8.
These numbers are multiplied by 4096 compared to Cisco numbers.

So you are basically saying to set a root switch i.e.: core switch to 0 and then the rest of the switches at 1?
Well, you wouldn't typically set all the other switches to 1. Just the switch that you would like to be the root should your primary fail.
ASKER
So your saying just set the root at 0 and another to 1 as backup and then just leave the rest?
It really all depends on the topology. If you have redundant links, then you would want to specify which switch would be the backup root so the redundant link is properly utilized. If you have more than one redundant link, then you would define the next switch to be the root.
If you have no redundant links, then this is all moot as the root location is irrelevant.

So if there aren't redundant links then it basically functions like any other STP? Are you referring to redundant links to one switch like a ether channel link?
Yes.
And non-etherchannel redundant links.

ASKER
If you were doing ether channel then how would you specify a switch to be a root and a backup?
Etherchannel doesn't impact STP configuration.

I didn't think so. Thanks for all your great info and help!
