I dont know if this is the correct forum to discuss and appologize if mistakenly posted.
In a ciscopress switching book "BPDU Filtering" section it stated:
" BPDUs are sent on all switch ports—even ports where PortFast has been enabled."
Few lines below its says:
"Switch(config)# spanning-tree portfast bpdufilter default"
"All ports that have PortFast enabled also have BPDU filtering automatically enabled."
Its really confusing if BPDU Filtering is automatically enabled on ports that has PortFast enabled than how come BPDU's are sent on Ports with PortFast enabled.
I would appreciate anyone can explain the difference.
