When OpenBSD was pissed off by proprietary HSRP protocol designed by Cisco, they decided to implement their own protocol (not compatible with HSRP) and use the same IP protocol number 114 without IANA approval. http://en.wikipedia.org/wiki/Common_Address_Redundancy_Proto... This created a serious mess for system administrators and gives a good example of how to handle compatibility and standards related issues ;)
I guess IANA should have given them a protocol number like they requested then, instead of playing politics because cisco employees run the organization.
Sure, but OpenBSD could have chosen some reasonably safe number that would not be in obvious conflict with Cisco equipment and would make users life easier. Instead they decided to have a childish revenge on Cisco.
It didn't make our life any harder, and using a different number wouldn't make our life any easier. We use cisco, juniper and openbsd, this caused exactly zero problems.
Yeah, that is a hilarious attempt to misrepresent the situation. Notice how he pretends they did it "to strike back", when they actually did exactly what he wants (try to get a number from IANA) and they refused to give them one because "that's just VRRP but different, it doesn't deserve its own number". The right choice was taken away from them, all they could do is use a number that is either used already, or will be handed out later. They chose the least bad option of using the number of VRRP, which IANA claimed they were too similar to.
