HSRP vs VRRP for IPv6 on IOS-XE - rekindling an old flame

It's a good argument Owen. Unfortunately it looks like VRRP is not an 
available feature on the ASR for IPv6 FHRP. I'm still trying to confirm 
it but it is definitely not configurable in my version of code and if 
it's "just coming out" in a "new release" there is no way I'm jumping in 
with both feet. I'll have to stick with HSRP and LL addressing. If 
anyone knows different please let me know. Thanks

PS: Yes, I still have some ISL. :( On legacy environments only though. I 
promise. Nothing new in years...
