There is nothing about SNMP that ties it to any particular network
protocol. You can run it over UDP in IPv6 just the same as you do in
IPv4. (Hell, you can run SNMP over AppleTalk or IPX.)

On a FreeBSD box, see ip6fw(8).

As I have pointed out, the _protocols_ will do fine. OTOH, finding
_products_ and applications that run these protocols over IPv6 might
be a little harder.

They are not really "two" branches. Most of the IPv6 specific code is
in netinet6. There is IPv6 code in netinet where there is
interoperability between the two. Most of the IPv6 code you see in
netinet is for the transport layer stuff. Duplicating the TCP and UDP
code in both would present an opportunity for drift and be difficult
to maintain.
