Rapid Spanning Tree Protocol (RSTP)

RSTP uses the process described in 

Table 18-1

 to avoid loops.

A spanning tree running in STP mode can take up to one minute to rebuild after a topology or 
configuration change. The RSTP algorithm provides for a faster recovery of connectivity 
following the failure of a bridge, bridge port, or a LAN. RSTP provides rapid recovery by 
including port roles in the computation of port states, and by allowing neighboring bridges to 
explicitly acknowledge signals on a point-to-point link that indicate that a port wants to enter 
the forwarding mode.

In rapid mode, the rapid transition of a port to the forwarding state is possible when the port is 
considered to be part of a point-to-point link, or when the port is considered to be an 

edge

 

port. An edge port is one that attaches to a LAN that has no other bridges attached.

Table 18-4: RSTP port states 

State

Meaning

DISABLED

STP operations are disabled on the port.

DISCARDING

The port does not participate in frame relay. The forwarding process 
discards received frames and does not submit forwarded frames for 
transmission.

LEARNING

The port is enabled for receiving frames only, and the learning process 
can add new source address information to the forwarding database. 
The port does not forward any frames.

FORWARDING

The normal state for a switch port. The forwarding process and the 
Spanning Tree entity are enabled for transmit and receive operations on 
the port.
