I was planning to load balance our 4506 core switch with a Cisco 3750G switch. Let me know how we can have it. Ay possibility that both switch can be configured as VTP servers, so that if 4506 switch goes down, then the 3750G switch can take it over?
You can have two VTP servers in a VTP domain i am currently having a live setup based on this setup the only process I follow here is that the VLAN addition,deletions are reflected manually on both the VTP servers in the domain and hence there is no issue of the conflict rising
The updation would certainly happen between the VTP servers. If I were you, I would have approached it in the way as mentioned below :
1. Configure the VTP domain settings on all the switches and configure only one server as the VTP server.
2. Once the VTP domain gets stabilize, set the other switch that you want to configure as VTP server to revision number 0.
3. Once the new switch is set to the same VTP domain name with revision number 0 and configured as VTP server, connect it to the LAN. This way it will inherit all the VTP settings along with the new configuration revision number.
4. Once this is done you will be all set to go with the VTP servers.
