Chapter 36: Spanning Tree and Rapid Spanning Tree Protocols

482

Section VI: Spanning Tree Protocols

Overview

The Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol
(RSTP) guard against the formation of loops in an Ethernet network
topology. A topology has a loop when two or more nodes can transmit
packets to each other over more than one data path. The problem that
data loops pose is that packets can become caught in repeating cycles,
referred to as broadcast storms, that needlessly consume network
bandwidth and that can significantly reduce network performance.

STP and RSTP prevent loops from forming by ensuring that only one path
exists between the end nodes in your network. Where multiple paths exist,
these protocols place the extra paths in a standby or blocking mode.

STP and RSTP can also activate redundant paths if primary paths go
down. So not only do these protocols guard against multiple links between
segments and the risk of broadcast storms, but they can also maintain
network connectivity by activating backup redundant paths.

One of the primary differences between the two protocols is in the time
each takes to complete the process referred to as convergence. When a
change is made to the network topology, such as the addition of a new
bridge, a spanning tree protocol must determine whether there are
redundant paths that must be blocked to prevent data loops, or activated
to maintain communications between the various network segments. This
is the process of convergence.

With STP, convergence can take up to a minute to complete in a large
network. This can result in the loss of communication between various
parts of the network during the convergence process, and the subsequent
lost of data packets.

RSTP is much faster. It can complete a convergence in seconds, and so
greatly diminish the possible impact the process can have on your
network.

Only one spanning tree can be active on the switch at a time. The default
is RSTP.

The STP implementation on the switch complies with the IEEE 802.1d
standard. The RSTP implementation complies with the IEEE 802.1w
standard. The following subsections provide a basic overview on how STP
and RSTP operate and define the different parameters that you can
adjust.
