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

It's too early for me to say that. I know for HSRP I had to define a group for IPv4 and a separate group for IPv6. Since it looks like VRRP is out for me I haven't looked into that. And I have no idea about other options for other manufacturers or specific implementations (NSRP, GSLB, etc.). I'm still hoping someone on this thread from Cisco or elsewhere will confirm my findings. I'll update the thread with what our direct AS folks come back with as well.

Any idea what to do if you want to use a FHRP for >255 subinterfaces?
HSRP allows you to use the same group number under multiple subinterfaces, while VRRP doesn't. I don't know if this is only a Cisco limitation (giving preference to their child).

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.
