STP

Redundant Layer 2 Topologies

Redundancy

Simple network VLAN mangement
Starting point
Path Failure - Access to Distribution
Path Failure - Distribution to Core
Switch Failure - Distribution layer
Switch Failure - Core layer

Issues with Redundancy

Layer 2 Loops
Broadcast loops

Real-world Redundancy Issues

Non-Redundant network topology
Loops from 2 connections in the same switch
Loops from connections to a second switch
Loops int the cubicles
