Hi, we need to migrate our switching network (2 6513 and 8 4507 all running ios, we are using more than 200 vlan) from rapid-pvst to mst (we are going to interconnect some non-cisco switch). Is there any suggestion about this migration? Thank you.
Since you're having more than 200 vlan's, this suggestion of migrating from PerVlan RSTP(PVRSTP) to Multiple Spanning Tree (MST) is a good one. Before that ensure whether your cisco ios version supports MST feature. I think your catalyst switches all will support MST. It has2 main advantages.
1.Load Balancing,
2.Less cpu burden.
The following document explains in detail about MST:
