Hello everyone
I recently got IPv6 working at home LAN. My Android device (Google Nexus 5) is connected via wifi to LAN and LAN's core router is Map2N <http://routerboard.com/RBmAP2n>. I have a /64 on the LAN with "advertise" enabled to make ND to work and have autoconfig working on all devices. There are bunch of other layer 2 devices in LAN but all just acting as layer 2 transparently and core L3 remains on Map2N.
All works well for most part but only trouble I am getting is on Nexus 5 where after around 24hrs IPv6 stops working.
How, specifically, does it "stop working" on the Nexus 5? - temp addresses expired and does not generate new, valid, slaac addresses? - RA entry ages out and doesn't get refreshed? - cannot reach v6 gateway (ND fails somehow)?
Only unusual thing I notice at that time is that phone 4 IPv6 as opposed to 2 (autoconf and temporary randomised address). Seems like some kind of issue in way NDP works either on Microtik or phone. The fix I am doing from few days is to restart wifi and phone interface gets fresh (two) IPv6 addresses and all works well again.
Anyone facing similar issue? (Note: No issues on OS X or iOS which are in same LAN)
I can try DHCPv6 but I guess most of devices do not support it yet. (I see support for that in routerboard though).
Unless something's changed, DHCPv6 IA_NA isn't an option for getting an IPv6 address assigned to an Android device[1][2]
Thanks.
