CCNA (Hindi) Day 15 | How to configure VTP in packet Tracer (Server, Client, Transparent)

VTP, or VLAN Trunking Protocol, is a Layer 2 messaging protocol used in Cisco networks to synchronize VLAN configuration across multiple switches. It helps simplify network management by allowing administrators to configure VLANs on a single switch, which then automatically distributes the changes to other switches within the same VTP domain.
Key features of VTP:
VLAN Synchronization:
VTP allows switches to maintain consistent VLAN configurations by exchanging VLAN information.
Centralized VLAN Management:
Administrators can manage VLANs on a single switch (the VTP server), and the changes are automatically propagated to other switches in the VTP domain.
VTP Modes:
VTP supports different modes, including server, client, transparent, and off.
Server: Creates, modifies, and deletes VLANs and propagates changes to other switches in the domain.
Client: Receives VLAN information from the server and updates its VLAN database accordingly.
Transparent: Passes VTP advertisements to other switches but does not synchronize its own VLAN database.
Off: Disables VTP on a switch.
VTP Domain:
A group of connected switches that share the same VTP domain name and VLAN information.
Revision Number:
VTP uses a revision number to track changes to the VLAN database. When a change is made on a server, the revision number is incremented, and the updated information is sent to other switches in the domain.
