Extreme and HP Spanning tree config

[Tom_Taylor]

We're a majority Extreme shop but have a few HP switches in the mix. I was wondering if anyone could point me in the right direction for configuring spanning tree on the extreme stuff to play nice with HP ?

By the looks of things the root bridge keeps swapping at the moment.

we had to change HP switches spanning tree configuration to rapid-pvst from default mstp. and have enabled stp only for the required vlan.

Extreme switches are configured with pvst-plus.

Of course there is other configuration for stp too.

Can you post your stp config for a uplink port on the XOS side?
