Vtp not updating packet tracer

Rated 3.89/5 based on 880 customer reviews

There is no answer with configure trunk links so we have to choose the solution “change VTP mode to server and enable 802.1q”.

But this is a dangerous solution because this switch can “update” other switches with its VLAN database via VTP.

You can view the configuration commands I used in the video at the bottom of this page.

Oh – if you would like to see an EXCELLENT video training course that covers all aspects of VLAN configuration, switch configuration, and prepares you for the CCNP, please check out the Train Signal Cisco CCNP Training Video Series – 642-812 BCMSN Click Play to begin the video or Click Here to see the video in its full-size Configuration commands Router commands Interface fastethernet 4.1 Encapsulation dot1q 10 Interface fastethernet 4.2 Encapsulation dot1q 20 Interface fastethernet 4 No shutdown Show ip interface brief Show vlans Switch commands Interface fastethernet 2/0 Switchport access vlan 10 No shutdown Interface fastethernet 5/0 Switchport access vlan 20 No shutdown Interface vlan 10 Ip address x.x.x.x y.y.y.y No shutdown Interface vlan 20 Ip address x.x.x.x y.y.y.y No shutdown Show vlan brief Show interfaces switchport Show ip interface brief Show int trunk Boss, Actullay i have packet tracer 5.2 version, I wanted to configure a small lab for testing where router,switch,firewall,pc would communicate to each other but unable to do the same and need help from your side,if you provide the related i would be oblise to you.

Switching has become the standard for most company internal network infrastructure as each port maintains its own collision domain, and with the advent of VLANs further allow the engineer to segment the network into multiple, smaller broadcast domains.

In this tutorial, we are going to apply VLAN on packet tracer.

By using the “show spanning-tree” command as shown above, we learned that DSW1 is the root bridge for VLAN 20 (notice the line “This bridge is the root”).

From the output above we see Switch Company A cannot receive VTP updates from Switch Company B.

Therefore we should check the trunking links connecting two switches. VLANs 2–1000 are eligible for pruning but VLAN 1 has a special meaning because it is normally used as a management VLAN and is not eligible for pruning.

Therefore, we can deduce that the priority of DSW1 switch is lower than the priority of the CORE switch so it becomes the root bridge.

To make the CORE the root bridge we need to increase the DSW1’s priority value, the best value should be 61440 because it is the biggest value allowed to assign and it will surely greater than of CORE switch.
