Hi YD Park.
First question: The routing configuration is done automatically by
LISPmob. You should not modify it. If I'm not wrong you should still
have connectivity from the xTR once LISPmob is started. The traffic
generated by the own xTR is not LISP encapsulated. Could you send me "ip
route" and "ifconfig" of the router once LISPmob is started?
Second question: You will have to deactivate the NAT functionality of
the openWRT router in order it works.
Regards
Albert

Albert,
Thank you so much your kind help.
This information is very helpful for me.
Although I cannot configure proper test-bed yet, I will try to do it
with*focusing on just a WiFi *scenario not a LTE.
Unfortunatly, I cannot use Wireshark on the OpenWrt where is no
package of wireshark.
I have two questions.
*First question is*
I seen some post by googling that is
(http://mail.lispmob.org/pipermail/devel/2012-December/000038.html)
So I type below lines Immediatly after running the lispmob on the xTR.
route add 0.0.0.0/1 <http://0.0.0.0/1> dev lispTun0 proto static
default via 141.223.84.120 dev eth1 metric 100
141.223.84.0/24 <http://141.223.84.0/24> dev eth1 proto kernel scope
link src 141.223.84.120
128.0.0.0.1/1 dev lispTun0 proto static
Consequntly following is result of 'route' command (ANMCGW.postech
mean my GW 141.223.84.99)
##############################################################
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface
default * 128.0.0.0 U 0 0 0
lispTun0
default ANMCGW.postech. 0.0.0.0 UG 0 0 0 eth1
128.0.0.0 * 128.0.0.0 U 0 0 0
lispTun0
141.223.84.0 * 255.255.255.0 U 0 0 0 eth1
153.16.0.0 * 255.255.255.0 U 0 0 0 br-lan
#############################################################
Unfortunatly when I type above lines, I cannot access Internet via xTR.
So, I assign IP addr(EID) to lispTun0 as follow
ifconfig lispTun0 153.16.70.240
Then, I can access Internet via xTR eventually. But, routing table
have been changed after assigning IP to lispTun0 as follow.
#############################################################
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface
default ANMCGW.postech. 0.0.0.0 UG 0 0 0 eth1
141.223.84.0 * 255.255.255.0 U 0 0 0 eth1
153.16.0.0 * 255.255.255.0 U 0 0 0 br-lan
#############################################################
Is this step normal?
*Second question is,,*
You said that I should assign EID to LAN interface of xTR and to
streaming server.
Then, does LAN interface mean br-lan interface of xTR?
I have statically assigned EID(153.16.70.241) to br-lan interface,
and EID((153.16.70.242) to streaming server that connected to xTR.
However, the PING from streaming server to smartphone does not work
while DEBUG message of xTR say that "141.223.84.120 is not Local EID"
141.223.84.120 is IP address (RLOC) of xTR router.
I think the reason is that when streaming server send PING message,
the source address is NATed to IP address of xTR (141.223.84.120) so
that lispmob of xTR generate the debug message ( "141.223.84.120 is
not Local EID").
I cannot understand what is wrong :(
Would you pleas give your opinion?
Best,
YD Park.
