VTP, which stands for VLAN Trunking Protocol, plays a crucial role in managing VLAN configurations across multiple switches within a network. By default, VTP sends out advertisements every 30 seconds to ensure that all switches in the same VTP domain are synchronized with the latest VLAN information. This interval helps to maintain VLAN consistency across network devices, allowing them to promptly update their configurations when changes occur, such as adding or deleting VLANs.

The 30-second interval strikes a balance between timely updates and network efficiency, minimizing unnecessary bandwidth consumption that could occur if updates were sent more frequently. Understanding this default behavior is essential for effective network management and troubleshooting VTP issues.
