I’m sorry, but this is 100% incorrect.  

HSRP comes from Cisco, but Cisco originally decided to not release the protocol to the IETF.  [Stupid play on their 
part, but water under the bridge.]  The IETF, realizing that this was useful technology, designed VRRP as a competitor 
to HSRP.  Once that was well on its way to standardization, Cisco realized it missed the boat and finally publicly 
documented HSRP.

Please get your facts straight.
