Verify VLAN works

Can we see traffic on it?

$ ifconfig eth0.2 up
$ tcpdump -i eth0.2 -n
tcpdump: WARNING: eth0.2: no IPv4 address assigned
tcpdump: listening on eth0.2
23:38:44.947528 arp who-has 130.95.2.4 tell 130.95.2.128
23:38:44.947548 arp who-has 130.95.2.4 tell 130.95.2.128

You should see traffic here. If you don't see traffic, check that 
there is no VLAN filtering on the switch you have plugged into.

All that remains is to place an IPv6 address on the interface.
