This isn't PAGP vs LACP again is it? Can someone show me a sunset 
document for HSRP from Cisco? Yes, VRRP, I use it as well. But that's 
not the point. The point is that it's a feature from a vendor that lacks 
parity across the product suites. Like most of the folks out there, I 
run IOS, NX-OS, IOS-XE, etc and that's just from Cisco. Feature parity 
is a big gripe that doesn't have an easy solution. I feel for the 
vendors but at the same time I'm frustrated when I read a document on a 
function and realize afterwards I can only deploy it on "some" of my up 
to date products. That's the point.

I disagree. I was asking security vendors what they were doing about 
these kinds of future needs years ago. Many years ago. They all conceded 
that they had had similar requests from other customers but the demand 
wasn't there yet. They should have had more vision on their road maps 
but they focused on basic functionality of the protocol and not features 
beyond that and now they are playing catch up. I understand, they were 
focused on what features were getting the attention. That's business. 
But everyone knew the depletion rates and everyone knew that whether the 
pompous USA wanted it or not IPv6 was coming in the late 2000s and early 
2010s. So they should have been more diligent. You can pull up any 
marketing document from any vendor and they will tell you IPv6 is fully 
supported. But when you implement features (who the heck runs a default 
config these days?) you really test the functionality of the product.

I agree. Stability. But a stable platform that doesn't have the features 
I need is not a stable platform I can invest in. Cart before horse.
