We are implementing this topology in our customer network.
Core routers are 7609-S connected via 10G links to each other and 1G links to the customer platform which contains 3650 cisco switches and Sun
The problem is that core switches in each site run MSTP, however 3560 switches run PVST. The solution works fine since both protocol are compatible but we have facing some problem especially when troublshooting or when adding new vlans (loops,...).We couldn't find any valuable document describing the installation and troubleshooting a network with PVST and MSTP.
So what we need to know if there's some technical references about this subject and what kind of commun problems we risk to face with this type of topology.
