<div class="moz-cite-prefix">Hi Kevin,<br>
<br>
I have been checking and it seems that this behavior I was
describing started in Android 5. Apart from moving the routes from
the main route table to interface specific tables, it seems that
the routes we add in the main table are ignored. Unfortunately, to
allow OOR works in root devices, we need to do big changes and at
this moments we don't have the required time resources. If you are
interested to do it, we will be glad to assesorate you. <br>
<br>

nothing is written to the OOR log file. Does the current

Hi Kevin,<br>
<br>
OOR in root mode works like the linux version of OOR.<br>
<br>
<ul>
<li>We define the RLOC interfaces in the configuration
file</li>
<li>We obtain the IP address and the gateway
associated with the interface (OOR needs to have a
gateway defined for each interface despite they have
different metric)</li>
<li>Add two routes to get all the traffic and overpass
the gateways:</li>
<ul>
<li><!-- <a href="http://0.0.0.0/1" target="_blank"> -->0.0.0.0/1<!-- </a> -->
dev lispTun0 proto static</li>
<li><!-- <a href="http://128.0.0.0/1" target="_blank"> -->128.0.0.0/1<!-- </a> -->
dev lispTun0 proto static</li>
</ul>
<li>Assign EID to the lispTun0 interface</li>
<li>For each RLOC address we create a new routing
table with a higher priority than the main table .
We send to this table all packets with source
address the RLOC IP.</li>
<li>We add to the new table the gateway route
associated with the RLOC interface -> Once the
packet is encapsulated will be reach this table and
sent through the gateway</li>
<li>Same process for IPv6<br>
</li>
</ul>
Example once OOR is started:<br>
<br>

We obtain the gateway from the main routing table.<br>
<br>
Previous to Android version 6, the routing in Android
worked like in Linux (what I explained before). From
Android 6 this has changed. The gateway of the
interfaces is no longer stored in the main routing
table. Instead of this, a new table is created for each
interface and it is in this table where the gateway is
stored. For instance, I show you the information of my
phone (OOR is not running):<br>
<br>
$ ip route<br>
<!-- <a href="http://10.61.76.252/30" target="_blank"> -->10.61.76.252/30<!-- </a> -->

32000: from all unreachable<br>
<br>
$ ip route show table 1012<br>
default via 10.61.76.254 dev rmnet_data0 proto static <br>
<br>
<br>
If you check the OOR log file you will see that the
system is not able to find the gateway and as a
consequence it can not finish with the process I
explained before.<br>
Here you have two options. Use a device with an Android
version previous to 6 to focus in your case or try to
solve this problem. If you try to solve it, considerer
that you not only have to know the gateway but also
detect the change of gateway through netlink.<br>
<br>
Another thing you should know is that the netconf module
to configure OOR while runing is only available in
Linux. If you want to change OOR configuration in
Android ( add a new RLOC interface, change MS, change
EID ...), you have to restart OOR.<br>
<br>
If OOR stops without reason, the first thing to check is
the log file to try to find any clue.<br>

You should select the interface that has
an IP assigned. In my device the name is
rmnet_data0. You can check it using "ip

</span> I think you have
selected the wrong intrefaces
in the RLOC interface
selection. You should select
something like wlan0, rmnet0
(the interfaces with an IP
selected). If your RLOCs are
behind NAT, you will need to
select NAT Traversal Aware. <span>

</span> I am not an expert in
Android but the last time we
tried to select the output
interface we couldn't. By
default Android only have one
active interface that you can
not select (if you are
connected to wifi I think you
can not choose to use the LTE
interface to send data). May
be it is possible to do it if
you have a rooted device but
we didn0t have time to work
with this. On the other hand,
we only have support for root
devices for Android versions
previous to 6. Android 6 and
above changed the way to
implement the network and we
haven't had time to adapt OOR
to it. For this devices we
only support the none root
version of OOR which is based
on the VPN API of Android. As
far as I know, with VPN API
you can not select the output
interface.<br>
