adjusting the type of protocol messages the RSTP node transmits, as
described below:
- STP Mode – If the switch receives an 802.1D BPDU after a port’s
migration delay timer expires, the switch assumes that it is
connected to an 802.1D bridge and starts using only 802.1D
BPDUs.
- RSTP Mode – If RSTP is using 802.1D BPDUs on a port and
receives an RSTP BPDU after the migration delay expires, RSTP
restarts the migration delay timer and begins using RSTP BPDUs
on that port.
Example
