VTP, or VLAN Trunking Protocol, is a Cisco proprietary protocol used to manage VLANs across a network of Cisco switches. VTP simplifies VLAN configuration and management in a network by propagating VLAN configuration changes from one switch (the VTP server) to other switches (VTP clients) within the same domain.

Key Features of VTP:
VLAN Consistency: Ensures all switches in the same VTP domain have consistent VLAN information.
Centralized Management: Allows VLAN creation, modification, and deletion on a single VTP server, which propagates changes to all client switches.
Reduced Manual Configuration: Eliminates the need to manually configure VLANs on each switch.
VTP Modes:
Server Mode:

Default mode for Cisco switches.
Can create, modify, and delete VLANs.
Propagates VLAN information to other switches in the VTP domain.
Client Mode:

Cannot create, modify, or delete VLANs.
Receives and applies VLAN updates from VTP servers.
Transparent Mode:

Forwards VTP advertisements but does not apply them.
VLANs must be manually configured and are not advertised to other switches.
Off Mode:

Does not participate in VTP or forward VTP advertisements.
VLANs must be manually configured.
VTP Versions:
Version 1: Basic functionality with support for Ethernet VLANs.
Version 2: Adds support for Token Ring VLANs and is backward-compatible with version 1.
Version 3: Enhances functionality, including support for extended VLANs (1006-4094) and better authentication.
How VTP Works:
VTP Domain: A grouping of switches that share the same VTP domain name and password.
Advertisements: VTP servers send periodic updates (advertisements) containing VLAN configuration information.
Configuration Revision Number: A number that increments with every VLAN change to ensure that the latest configuration is applied.
Best Practices:
Use VTP version 3 for enhanced security and features.
Set VTP to transparent mode if you do not need centralized VLAN management to avoid accidental overwrites.
Secure VTP with passwords to prevent unauthorized updates.
