I've question, it's possible active rapid spanning-tree and spanning-tree backbonne-fast on the same switch ?
Go to Solution.
the answer is that Rapid STP includes the equivalent of backbone fast in its behaviour.
The backbone fast convergence optimization is built in in Rapid STP so you don't need to enable it.
With Rapid STP is very important to define the user facing ports using spanning-tree portfast. This helps to improve convergence by limiting the ports on which a synchronization wave is propagated.
Hope to help

Thank You Guiseppe,
I actived to show the result on the switch and you're right.
Here is the result :
Switch is in rapid-pvst mode
Root bridge for: VLAN0001
Extended system ID is enabled
Portfast Default is disabled
PortFast BPDU Guard Default is disabled
Portfast BPDU Filter Default is disabled
Loopguard Default is disabled
EtherChannel misconfig guard is enabled
UplinkFast is disabled
BackboneFast is enabled but inactive in rapid-pvst mode
