Migration from PVST to Rapid STP

We are planning to migrate from PVST mode to RSTP mode in our Production Network having 6 Switches (6509). We have a critical trading network so need to be aware of the impact of the migration and the necessary configuration other then

spanning tree mode rapid-pvst

Please discuss.

Re: Migration from PVST to Rapid STP

Hello,

First, I suggest reading the following document that discusses a migration scenario from PVST+ to RPVST+:

http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a00807b0670.shtml

Migrating to RPVST+ will be most probably disruptive to the network operation, therefore it is recommended to plan this operation to a maintenance window. The outages will be caused by all ports on the reconfigured switch to going into Discarding state and negotiating their RSTP roles and states anew.

Please feel free to ask further!

Best regards,

Peter
