I added IP6 addresses on my filers. The config looks like this now:
vmshe-fas3070-12> ifconfig -a
...
e0c: flags=148043<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM> mtu 1500
inet6 2008:cccc:bbbb:aaaa::4 prefixlen 64 tentative
inet6 fe80::2a0:98ff:fe0a:1d59 prefixlen 64 scopeid 0x2 autoconf tentative partner e0c (not in use)
ether 00:a0:98:0a:1d:59 (auto-1000t-fd-enabling) flowcontrol full ..
vmshe-fas3070-11> ifconfig -a
e0c: flags=4948043<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM,NOWINS> mtu 1500
inet6 fe80::2a0:98ff:fe0c:8a3d prefixlen 64 scopeid 0x2 autoconf
inet 192.168.0.90 netmask 0xffffff00 broadcast 192.168.0.255

partner e0c (not in use)
ether 00:a0:98:0c:8a:3d (auto-1000t-fd-up) flowcontrol full
They both can ping one another...
vmshe-fas3070-12> ping6 2008:cccc:bbbb:aaaa::7
PING6(56=4088 bytes) 2008:cccc:bbbb:aaaa::4 --> 2008:cccc:bbbb:aaaa::7
16 bytes from 2008:cccc:bbbb:aaaa::7, icmp_seq=0 hlim=64 time=1 ms

But cannot ping on the fe80 addresses.

There aren't any firewalls up. My cisco switch has all the ports on the same default vlan.
I added a "2008" IP to the vmkernel but I can't ping it.

Unfortunately, I don't have anything else on this private network with IPv6 to ping....hmmm
