Sažetak
A campus network is an enterprise network that
consist of many connected LANs that are all
usually in the same geographic area.
According to the Network Hierarchy, a campus
network has three separated layers - Access Layer,
Distribution Layer and Core Layer.
Spanning Tree Protocol was designed to identify
and prevent switching loops with disabling or
blocking ports. It also provides network link
redundancy so that a Layer 2 switched network
can recover from failures without intervention
in a timely manner. That explains importance of
distribution layer or Layer 2 in the successful
operation of Spanning Tree Protocol.
The process of building STP Protocol is
multistage process of electing Root Bridges,
Root Ports, Designated Ports and putting ports
in blocked state in order to prevent formation
of switching loops. STPs alternatives such as
SPB and MLAG have not yet received broader
adoption because they are either tied to specific
manufacturers or standards are still implemented
in a non-compatible ways and are therefore
mostly used in a large data center networks.
Due to limited support for most other options,
STP is still the only option in heterogeneous
environments.
