RPVST+ Max VLAN's

Hi,

Can anyone tell me what the max supported amount of VLAN's is when running RPVST+ on a 5412zl 2 at the core with 2920 as edge switches.

Also does anyone have a calculator to be able to calculate the overhead when running 300+ vlan's with Spanning tree enabled, I just need some figures to be able to advise against it.

 

Thanks.

Re: RPVST+ Max VLAN's

You can have 500 routed VLANs.

I can't imagine what kind of a design would have that many VLANs though...

Maybe somebody has used VLANs where port-isolation might have been better...?
