Hello Juan Carlos Pacheco 


Thank you for guiding through the steps mentioned in Thread Border Router using Linux + KW as Host Controlled Device with Serial TAP for DHCPv6-PD. We are following the steps provided by you, however, we are still facing the issue.



a) Linux PC (Ubuntu 14.04)

b) FRDM KW41Z flashed with a Host controlled device application

c) FRDM KW41Z flashed with a router eligible end device (REED)

d) OpenWrt Router configured with ULA prefix.


FRDM version:
b) IEEE 802.15.4 MAC: v5.3.6
c) NXP Thread: v1.1.1.20

d) Thread SDK: SDK_2.2.0_FRDM-KW41Z_LINUX


We have done bridging of eth1 and threadtap0 interface. I am not able to ping Router's IPv6 address 2001:2002:2003::1 from Linux PC, but still able to ping from REED. However, after some time ( approx. 50-60 ping response are received), ping response does not come from REED as well.


I have attached a file for reference, which contains:

a) steps.txt: steps used for configuring Linux machine as a border router.

b ifconfig.txt: output of "ifconfig" command.

c) IPv6Netstat.txt: output of "netstat -rn -A inet6" command.

d) routerEligileEndDevice.txt: console of router eligible end device.

e) linuxBRMachine.txt: log of ping command in Linux machine configured as a border router.
