I'm tasked to replace our core switches which run Extreme 6800's. You are right
that some older gear says they support IPv6,
but then you find out it's not 100% fully compliant. Our switch is about 6-8
years old I beleive so it's time to update them.
We're thinking about the Cisco 6504e. Anything that is pretty modern that we
feel will yield us another 6-8 years.
I only have a handful of juniper firewalls laying around for lab equipment, so
I don't really have that much experience with them.
We also need to get IPv6 space from ARIN so that we can fully support IPv6
natively. Our plan is to dual-stack our edge routers,
so it is ultimately up to the endpoints to support IPv6. We don't want to deal
with any tunneling protocols like Teredo for IPV6.
