This site is provides lab scenarios for students who preparing for the Cisco exams and gain some practical experience with Cisco routers and switches with other vendors like Mikrotik and juniper. All labs have been created using real equipment. our labs is easy to use you don't need to pre-configure or any another thing just login into our remote server and follow the instructions . All Labs available for free to assist network operators and Cisco certification students with common problems or challenges that crop up in configuring Cisco networks.

VTP (Virtual Trunking Protocol)

VTP is a cisco proprietary protocol that reduce vlan administration effort in switch network.

Normally, If you define a vlans on a switch in switched network, you should added them also on other switch in switched network, this can be a home work if involving a large number of switches and is also prone to error.

VTP makes your life easy, VTP allows you to add, delete and rename vlans on a single switch and this information will propagated to all other switch in the VTP domain.

In this manner, VTP allows for more consistent vlan configuration and monitoring of vlan by central administration.

VTP has three different modes :
- Server
This is the default mode on all cisco switch, a switch must be in VTP server mode to be able to create, modify and delete vlans.

- Client
a switch in VTP client mode raceive information from VTP servers, but a VTP client cannot create, modify and delete vlans. so, switch that are in VTP client mode will just learn and pass VTP information.

- Transparent
a switch in transparent mode receive VTP and forwards the to any configured trunk links. they can create, modify and delete vlans in their own vlan database but the database is kept isolate from the VTP domain and isn't advertised at all to other parties.

Let's find out how it's works for free only at freelabnetworks.blogspot.com.

If I’ve missed anything please speak up in the comments and let me know.
