Chapter 7 Configuring STP and RSTP

Interoperability with IEEE 802.1D STP

• Protocol migration—For backward compatibility with IEEE 802.1D switches, RSTP selectively

sends IEEE 802.1D configuration BPDUs and TCN BPDUs on a per-port basis.

When a port is initialized, the timer is started (which specifies the minimum time during which

RSTP BPDUs are sent), and RSTP BPDUs are sent. While this timer is active, the switch processes

all BPDUs received on that port and ignores the protocol type.

If the switch receives an IEEE 802.1D BPDU after the port’s migration-delay timer has expired, it

assumes that it is connected to an IEEE 802.1D switch and star ts using only IEEE 802.1D BPDUs.

However, if the RSTP switch is using IEEE 802.1D BPDUs on a port and receives an RSTP BPDU

after the timer has expired, it restarts the timer and starts using RSTP BPDUs on that port.

Interoperability with IEEE 802.1D STP

A switch running RSTP supports a built-in protocol migration mechanism that enables it to interoperate

with legacy IEEE 802.1D switches. If this switch receives a legacy IEEE 802.1D configuration BPDU

(a BPDU with the protocol version set to 0), it sends only IEEE 802.1D BPDUs on that port.

However, the switch does not automatically revert to the RSTP mode if it no longer receives

IEEE 802.1D BPDUs because it cannot determine whether the legacy switch has been re moved from the

link unless the legacy switch is the designated switch. Also, a switch might contin ue to assign a boundary

role to a port when the switch to which this switch is connected has joined the region.
