VRRP and IPv6

ccnxjr

Trying to put together a VRRP sim using IPv6 in GNS3
This using the following:

Software, 2600 Software (C2691-ADVIPSERVICESK9-M), Version 12.4(15)T6,



However when I'm trying to configure the IP address for a VRRP group IOS v 12.4 insists I use an IPv4 address.
I have an IPv6 address configured on the interface and I'm able to ping another IPv6 device on the same segment.
Here's the config on the interface as it is:
interface FastEthernet0/0
no ip address
duplex auto
speed auto
ipv6 address 2900:100:300::A/64
ipv6 enable

Am I using the wrong IOS version or device?

Thanks a bunch,

This is actually a good question. Research VRRP interaction with IPv6. If I find something out I'll report back.

VRRPv3 is too new. I don't think it is supported by Cisco yet.

Think it's supported by IOS XR.
Cisco IOS XR IP Addresses and Services Configuration Guide for the Cisco CRS Router, Release 4.1 - Implementing VRRP  [Cisco Carrier Routing System] - Cisco Systems
I was hoping that something in the IOS-12.X range might support VRRP using IPv6, since I didn't want to start learning "bad" habbits before taking the tests. Especially since the prompts are the same, i can see myself getting easily confused between the two IOSs.
You know, just until I get a firm grasp of the CLI in IOS 12.x , what i should expect from it and what it expects from me :P

Really was looking to implement this over a mixed platform shop, (thats why VRRP insted of HRSP) so I thought I'd start in an environment that was more familiar, Cisco

My boss already tackled the IPv4 end of things so was looking for brownie points in making the IPv6 end happen.
