I would like your suggestions to help me Migrating PVST to RSTP. We have 2 core switches (6509 - SUP 720) connected to each other via 2 TenGig links as port-channel. Rest all the Distribution Switches (L2) (4948) are connected to Core switches via 3gbps fiber port-channel and Access switches (L2) (4948) are connected to distribution switches via 2gbps fiber port-channel.
Primary core switch is currently the root bridge and secondary is secondary root bridge. Portfast and bpdufilter is enabled on all the access ports. Total we have around 45 (4948) switches.
We know that RSTP is better in converging but i just need your expert comments since its a Live environment.
