The Spanning Tree Protocol (STP) dates from 1985. This course explores in depth how the protocol works and the implications this has on network performance. We also study STP variants including 802.1w (RSTP) and 802.1s (MSTP).
What is 802.1D, what is STP, resilience, broadcast
storms, forwarding and blocking, single path.
Hands on Impact of broadcast storms, enabling disabling STP.
STP frames, BPDUs, root bridge election, blocked
ports, root ports, designated ports. STP path
Hands on Analysing STP, troubleshooting implications.
Hello timer, Forward delay timer, max age timer,
Topology Change Notification (TCN) BPDU.
Hands on STP convergence.
Bridge ID, Bridge priority, port priority, 30 second
delay, Edge ports, PortFast, root guard, loop
guard, BPDU guard.
Hands on Root bridge positioning, improving STP convergence.
802.1w, Improvements, convergence times. RSTP
bridge port roles, RSTP switch port states. Edge
ports, link ports.
Hands on RSTP configuration and convergence.
Access/untagged ports, trunk/tagged ports,
PVST, PVST+, RPVST, MISTP, MSTP and
802.1s. MSTP BPDUs. Instances, Load
balancing, impact on CPU.
Hands on MSTP load balancing.
Regions, Virtual bridges, domains.
Hands on STP, RSTP and MSTP interoperation.
"Hard concepts were explained very simply"
"Excellent presentation - very good course structure."
This structured training course seeks to build upon workbook learning through the use of group exercises, dynamic discussion and individual tasks in order to deliver an engaging and interactive module that will ensure all candidates are able to transfer their new skills into the workplace.
