Switching STP HSRP VLAN RSTP BPDU guard vs BPDU filter

Question

Accepted Answer

Explanation of STP, HSRP, VLAN, RSTP, BPDU guard and BPDU filter in network switching.

STP (Spanning Tree Protocol) is used to prevent loops in a network by blocking redundant paths.
HSRP (Hot Standby Router Protocol) provides redundancy for IP networks by allowing multiple routers to share a virtual IP address.
VLAN (Virtual Local Area Network) is a logical grouping of devices on a network, allowing for better network management and security.
RSTP (Rapid Spanning Tree Protocol) is an updated version of STP that provides faster convergence times.
BPDU (Bridge Protocol Data Unit) guard protects against unauthorized switches being added to the network by disabling the port if a BPDU is received.
BPDU filter prevents the port from sending or receiving BPDUs, which can be useful in certain situations such as when connecting to a non-STP aware device.
