How to Configure Spanning-Tree Bridge ID – Briefly Explained

When configuring a specific switch as a root bridge, the bridge ID priority value must be adjusted to be lower than the bridge priority values of all the other switches on the network. There are two different methods for configuring the bridge priority value on a Cisco Catalyst switch. Method 1 To ensure the switch […]

What is RSTP and Rapid PVST+: Exclusive Details

RSTP- IEEE 802.1w is the advanced version of STP, providing faster convergence than CST but holding with the same single root bridge in the topology. Most parameters in RSTP are the same as STP, so users who understand STP can effortlessly configure the RSTP. Rapid PVST+ is Cisco’s proprietary implementation of RSTP that operates on […]

Spanning Tree – Port Roles

IEEE 802.1D Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) use the Spanning Tree Algorithm (STA) to decide which switch ports on a network must be put in a blocking state to prevent loops. The Spanning Tree Algorithm designates one switch in the network as the root bridge. The root bridge is considered […]

Network Redundancy Revolutionized: Achieve 99.999% Uptime

Network redundancy ensures high availability and reliability in modern networks by providing alternate paths for data transmission, allowing seamless failover if a link or device fails. In CCNA/CCNP contexts, it shares traffic loads, boosts capacity, and employs protocols like Spanning Tree Protocol (STP) for Layer 2 loop prevention, or First Hop Redundancy Protocols (FHRP) like […]
