◆
RSTP supports connections to either RSTP or STP nodes by monitoring
the incoming protocol messages and dynamically adjusting the type of
protocol messages the RSTP node transmits, as described below:
In normal 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.
◆
In compatible mode, if the switch receives an 802.1D BPDU (i.e., STP
BPDU) after a port's migration delay timer expires, the switch assumes
it is connected to an 802.1D bridge and starts using only 802.1D
BPDUs.
