How do I verify if IPv6 is setup correctly for the Z/IP Gateway?
Answer
Under normal circumstances, Z/IP Gateway will autoconfigure the IPv6 stack on the host it runs on, however it may not be able to do so on certain hosts.
To verify that IPv6 connectivity is working go through the following steps:
Check the output of route -6:
root@beaglebone:~# route -6
Kernel IPv6 routing table
Destination Next Hop Flag Met Ref Use If
::1/128 :: U 256 0 0 lo
fd00:aaaa::/64 :: UAe 256 0 1 br-lan
fd00:bbbb::/64 fd00:aaaa::3 UG 1024 0 0 br-lan
fe80::/64 :: U 256 0 0 br-lan
fe80::/64 :: U 256 0 0 tap0
::/0 :: !n -1 1 20 lo
::1/128 :: Un 0 1 10 lo
fd00:aaaa::7aa5:4ff:fefd:dc51/128 :: Un 0 1 0 lo
fe80::7aa5:4ff:fefd:dc51/128 :: Un 0 1 0 lo
fe80::bcc2:8ff:fe99:416f/128 :: Un 0 1 0 lo
ff00::/8 :: U 256 1 0 br-lan
ff00::/8 :: U 256 0 0 tap0
::/0 :: !n -1 1 20 lo
root@beaglebone:~#
In this case there are two particularly interesting lines:
fd00:aaaa::/64 :: UAe 256 0 1 br-lan
Which tells that the address range fd00:aaaa::/64 is reached through the br-lan. And
fd00:bbbb::/64 fd00:aaaa::3 UG 1024 0 0 br-lan
Which tells that the PAN is reached through Z/IP Gateway.
Further check that the br-lan has an address with the same prefix as Z/IP Gateway using ifconfig:

Here it can be seen that this is the case:
If any of these checks fails, rectifying actions needs to be carried out.
