Can STP, RSTP,PVSTP and MSTP support other vendor  except cisco switch?

[Kasun Bandara]

PVST is cisco proprietary. others are OK.

[krahulbgp]

except pvst all mstp,rstp,pvst+ will support for other vendor

am i right ?

You didn't mention pvst+ in your OP, but as @Kasun Bandara mentioned for pvst, the plus version would also be Cisco proprietary.

As such, if another vendor has licensed it from Cisco, or Cisco has granted it public usage, another vendor might support it.

STP, rapid-STP, and MSTP are all "public', although other vendors might not support them.  (Likely every vendor would support STP.)

friend any protocol is authz by IEEE it can use by other vendor
