Diameter issue with MST

Please, is there any limit to diameter network in a network using MST (802.1s) ?

Thanks,

Cleber

Re: Diameter issue with MST

Yes, but it's much less restrictive that what was recommended for regular STP.

Between MST regions, you are basically limited by the max-age parameter in terms of number of bridges a BPDU can go through. Inside an MST region, the parameter is max-hops. No need to be close to the limits, if you have a large diameter you can increase max-age with no real impact on convergence time.

Francois
