vtp domain

Hi,

would appreciate some advise and clarification on the following:

1) when 2 switches are configured with different vtp domain, but both configured with e.g. vlan 500, they would be able to communicate? should be yes?

2) when one of the switch is updated to the same vtp domain, would it cause downtime to the existing vlan 500 users? should be no?

Thanks,

Christina

Re: vtp domain

Hi Christina,

1) Yes, VTP is simply meant to propagate VLAN configurations, so as long as both switches are configured with Vlan 500.

2) If one of the switches is configured to have a VTP domain match, it should not cause any downtime. The VTP configuration revision will be reset to 0, so there will be no possibility of it overwriting the VTP server's VLAN database.

HTH,

Bobby

Re: vtp domain

when you update switch to the same vtp domain ...it will have configuration revision number 0... so it will syncronise its database from other serverswitch in the topology with the higher revision number ... so updating switch to the vtp domain will not cause any problem...

read the document on the following link:http://www.cisco.com/en/US/products/hw/switches/ps5528/products_configuration_guide_chapter09186a00801e8788.html

it is having good explanation for VTP with configuration

rate this post if it helps
