Loopguard in IEEE standard

Hi everyone!

 

As I understood, " loopguard" is a proprietary Cisco feature and it seems to me that it has an important role in running STP.

So ... I have two questions:


1- Does anyone know the equivalent of the loopgaurd feature in IEEE 802.1D standard? Does an IEEE standard support loopguard-like feature?

2- Does MSTP or RSTP or PVST or...  need loopgaurd feature too?

 

Thanks,
Amir

Thank you, Paul, for your response! 

I took a look at 802.1 d and 802.1 Q documents quickly and I didn't find anything related to loopguard ( or even unidirectional link detection), so I guess these standards don't cover loopguard or something like that, right?
