PVRST vs PVRST+

[barrywells]

Hi There,

Sorry for the simplicity of this query. What are the differences

between PVRST and PVRST+, I have trawled the internet looking for this

answer but have been unable to locate it. I understand the differences

with PVST and PVST+ with the .1q trunking ability but have not been

able to locate information on PVRST and PVRST+.

A colleague suggested that maybe PVRST+ has portfast and uplinkfast

integrated and enabled by default if anyone could confirm/contrict this

i would be most grateful.

Many Thanks

Barry

Per-VLAN Rapid Spanning Tree (PVRST+) is the implementation of 802.1w on a per-VLAN basis. It is the same as PVST+ with respect to STP mode and runs RSTP protocol based on 802.1w.

I am confused.

Is it PVRSt or RPVST?

Is it different way of writing or they are different protocols?

I see them both.
