Question : MSTP Configuration on Procurve Equipment

We are moving from T1 connection from 12 sites running into a cisco 3660 to 12 pipes from charter running into a Procurve 5400.  Each site has a 5300.  After many attempt to bring these connection online.  I have realized STP is causing problems.  After chatting with a few people it seems I need to setup MSTP on my switches.  What I am looking for is a rough config or explaination on how to go about doing this.  I know I will need to trunk ports on both ends, but on our 5400 I've noticed you can only trunk up to 8 ports and I have 13.  

Right now this is my confiug

VLAN 1 (Default)
VLAN XXX (For our WAN Connections)
VLAN XXX (Site specific)

Answer : MSTP Configuration on Procurve Equipment

If it is isolated, the wan links need to be on their own subnets.  Ie: link to site 1 - 10.0.233.0 /30  link to site 2 - 10.0.233.4 /30 etc.  Otherwise your routing protocol will get all confused, and I can see spanning tree having a tough time trying to figure out what is going on... but the real issue is trying to set the layer 2 subnet throughout a wan of point to point links.
