Those were our same exact reasons as well. We were supporting multiple tenants and had a need for a large number of VLANs on the campus. The 3560s also had that 128 STP instance limit, and we were fast approaching it. We knocked it down to about 10 MST instances, giving us some flexibility as far as setting roots and costs.

It's quite good if your topology is simple but you have a lot of VLANs. Before we used a lot of STP instances, now we use two of them:) Also on the Cisco 2960 series platform you have an STP instance limit of 128.

Yeah. We see to it that our L2 STP domains are very small (if we can avoid it, no more than 4-6 devices each), and we need to go cross-city, it's EoMPLS instead of "STP + L2 all across the core". But our business is very much different from yours - less customers, and much more customized setups for each customer. We *do* have VLAN assignment conventions, and all that, of course :-) - but at least once a month we need to do something that's an exception for some reason - and then I'm quite happy not having to fiddle with MST vlan mapping. gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany [email protected] fax: +49-89-35655025 [email protected] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
