Re: VTP Server

Hi Cliff,

There is no direct command which you can use to change the VTP config revision number. Whenever you make some VTP configuration changes to vlan database like addition of vlans, deleting vlans the configuration revision number will keep incrementing by 1.

Talking about your client because you cannot create,delete or modify vlan information on client so the configuration revision number cannnot dirctly increment on VTP client and it only get synched with VTP server.

Before adding new client into your network make sure you change your VTP client to transparant first and then back to client which will put the config revision number to zero to new clients before they come up in your existing network.

Hope it helps.

Re: VTP Server

Hi Ankur,

I really appreciate your advice, but it seems that i will be force to proceed to other option :=), w/c is configure my 2 VTP Servers in different Domains, but my problem now is how will I route my other domain vlans (CISCO2) to the main domain(CISCO1)as well as access the internet,coz i only have one physical connection to my Gateway_Router w/c is in DOMAIN1 VTP Server and DOMAIN2 will have to pass through DOMAIN1 before it can access the Gateway Router to have internet access.

Examples of my vlan config are listed below:

Just correct my configs if you've seen errors and if i miss some settings.

Gateway Router:

IP Add: /24

ip route

ip route

ip route

ip route


Domain: CISCO1

VLAN1 IP Add: /24

VLAN10 IP Add: /24

VLAN20 IP Add: /24

ip route


VLAN1 IP Add: /24

VLAN30 IP Add: /24

VLAN40 IP Add: /24

ip route

*My aim is to be able to communicate 2 different DOMAIN VLANs and at the same time access the internet with only one physical connection to the gateway router.

Thanks Again

Re: VTP Server

there are 3 ways

1)change the VTP domain name for example from "cisco" to " abc" and then change it back to "cisco".

2)change the mode from server to transparent and then back to server

3) Clear config all ( but it will erase all your config , i am sure u dont want to do that :D )
