Our environment consists of over 800 access switches and 300+ vlans. We use the 3 layer model; core, distribution, access, with routing done at the core and distribution layers via OSPF.
At our old facility we had our core doing all the routing with about 100 vlans and 150 access switches. We had a VTP domain configured and VTP pruning was configured. We had situations where a device was added with a higher revision # and all the vlans were overwritten causing machines to lose access to the network till all vlans were re created. So moving to the newer larger facility we had designed our network without VTP to avoid this major flaw in VTP.
So with efficency in mind we would like to prue the downlinks to the access switches. With the amount of traffic that is being generated on our network this is starting to become a concern and with so many access switches this would be a large job to do manually. So my question is this:
Is there a way to prune the vlans on the down links to our access switches automatically. The key word here being automatically.
Does anyone have any suggestions on how we can configure or reconfigure our network to make it more efficient?
thanks in advance.
