In different scenarios, RSTP provides different protection functions, and the wrong statement about this statement is
A . The root protection feature is enabled for the specified port, and its port role can only remain as the specified port
B . When the anti-TC-BPDU packet attack feature is enabled, the number of times the switching device processes IC BPDU packets per unit time is configurable
C . after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed
D . Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state

Answer: C
