I want to configure HSRPv2 dual stack on my core-switches.
Information:
- Access1 is in VLAN 64, Acess2 in VLAN 65 and Access 3 in VLAN 66
- I have configured SVIs for each VLAN (IPv4 and IPv6).
- in the backbone (The yellow area) I am running OSPF (Dual Stack).
Here's the topology:
Questions:
How can I configure HSRPv2 for both, IPv4 and IPv6? Do I have to use a different standby-number for each address-family?
And which connection should be configured between Core 0 and Core1? Normal routing port or a trunk?
And when I configure HSRP for one SVI, how does the other router know that he should take part in this HSRP process? Just by configuring the same standby id one the other router?

I don't know your IP address structure, but i'll just use 172.26.0.0/24 as an example and a random IPv6 address (Remember this is just basic configuration):
Yes for each address family, the IPv4 standby group number has to be different from the IPv6 group, otherwise it wont work.
A normal trunk will suffice for HSRP to work.
I explained that here: HSRP - How do routers with equal standby-group find each other?
