Cisco CCNA Packet Tracer Ultimate labs: VTP Troubleshooting Lab. Can you fix the network?

#CCNA #PacketTracer #CCENT

This is a Packet Tracer VTP Troubleshooting lab. Can you fix the network?

VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products.


VTP packets are sent in either Inter-Switch Link (ISL) frames or in IEEE 802.1Q (dot1q) frames. These packets are sent to the destination MAC address 01-00-0C-CC-CC-CC with a logical link control (LLC) code of Subnetwork Access Protocol (SNAP) (AAAA) and a type of 2003 (in the SNAP header).

Transcription:

This is a VTP or VLAN Trunking Protocol troubleshooting lab.
In this lab, you need to troubleshoot the following issues.
When VLANs are added to switch 1, the switch on the left the VLANs are not replicated to other switches in the topology, so in other words, when a VLAN is added to the VLAN database, VTP is not synchronizing those VLANs to the other switches in the topology.

Now in this lab, you need to troubleshoot that and make sure that you fix the network so that when VLANs are added to switch 1, the other switches in the topology learn about the new VLANs.

In other words, you need to make sure that other VLAN database are synchronized.
Now in this lab, don’t make any changes to switch 1 except for adding additional VLANs. You need to troubleshoot the issues on the other switches. so don’t make any changes to the configuration of switch 1 apart from adding additional VLANs to prove that VTP is working properly.

Try to complete this lab without using the show run or show start commands.
Use other commands on the switches such as show VTP status or other commands to see what the problem is.

So as an example, show vtp status
shows me the status of VTP on the switch. Use show commands such as this to see what’s going on. See where the problems are and then fix the network. Try not to use show run or show start unless you really have to.

So can you fix this network?
Download the packet tracer file and see if you can fix the network yourself, otherwise watch the next video where I fix the network.

Lots of fun. Great little-hidden surprises. I really enjoyed it. Good job as always David!

Hello Sir!! Best network forum ??? Any suggestions!

I haven't done this lab yet but I bet the problem is a trunking issue.
