hsrp and rfc 2281

[sarahr202]

Hi everybody

My book says hsrp is cisco's proprietary protocol . The book also says rfc 2281 describes this protocol in detail.

My question is  how it could be possible for hsrp to be cisco's proprietary protocol but yet  still be defined by ietf rfc?

thanks and have a great weekend

Hello Sarah,

it looks like strange, however the RFC has been produced in the process to introduce VRRP as a reference

see

http://www.ietf.org/rfc/rfc2281.txt

This document reflects an existing deployed protocol.  The IETF does
   have a working group which is in the process of producing a standards
   track protocol to address the same issues.

= VRRP

And the authors are two people from Cisco and two  people from Juniper

Hope to help

Giuseppe
