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.

VRRP is to HSRP what 802.1q is to ISL...
I highly recommend using VRRP instead of HSRP because:
1. It is a more robust protocol 2. It is vendor agnostic 3. Being vendor agnostic it is more likely to have a continuing future.
Does anyone still use ISL?

Yeah I see the disconnect. I'm assuming that what I see is what I get. Which means I'm going to stick with HSRP. If our AS team gives me any good feedback that I can share I will do so. Thanks Nick.
XE: v4: HSRPv1, HSRPv2, VRRP v6: HSRPv2 Not particularly relevant to the original question - however, I'd like to mention that we've been using IPv6 VRRP on our Juniper routers for well over a year. No particular problems so far.
