-Disable vtp. Prune manually. 60 is not a large number. Just for comparison for one segment of our network we have well over 7000 Vlans and yes stp/vtp are disabled. We planned it that way. -Even if you choose to go L3 end to end. I wouldn't advocate for a total stp shutdown as has been advised unless you are very sure no one can attach a random switch or other bpdu generating device. You can start planning the transition though. Sent from my iPad On 27 Feb 2012, at 09:41, jim ndegwa <ndegwajim@yahoo.com> wrote:

Unless it was already mentioned, don't forget setup vlan trunk protocol (VTP) to better manage your VLAN spread across the multiple switches. Setup core-switch as server and access as clients. Prune vlans accordingly. Note VTP revisions when adding new switches or you might wipe out the core configuration if it happens to be lower than the newly added switch

Well still not enough to go with but.

With 60 vlans and I assume hsrp at the core running on a 6513:

I'd create two hsrp groups, one for odd and the other for even numbered vlans. This makes your traffic 'balanced' ....

Next i make a guess here that you have multiple switches each with multiple links to the core. To ensure no link goes to waste, make it such that the root ports for odd and even numbers don't use the same path. And only your 6513 can be the root bridge. Again I make an assumption.

Tune your stp appropriately. Use the guides below for guidance. Or leave the convergence defaults. However ensure the access switches never become root bridges.

While asking questions like this, it helps to throw in a topology, what you want to achieve, what you've tried, etc.....people otherwise second guess your requirements. It's like a request for quotation vs a request for information. The latter brings you marketing answers/guys.

Hahaha nope its not my home network but an entire cooperate network with around 60 vlans. Core-switch is Cisco 6513 so its pretty serious network.

If i chose PST, which of the earlier commands leads to faster convergence?

Note: I also have HSRP setup.

If he needs more granulated answers he'll have to give more info:-)

Guys,

Mburu did not mention the size of the network, to gauge it to the effort he wants to apply.
