User who did this - tiagogaspartgeio15 (tiagogaspartgeio15) 

Attached to Project - OpenWrt/LEDE Project
Summary - Prefix Delegation is broken
Task Type - Bug Report
Category - Packages
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Critical
Priority - Very Low
Reported Version - lede-17.01
Due in Version - Undecided
Due Date - Undecided
Details - Device problem occurs on: TP-Link TL-WA850RE v1

Software versions of OpenWrt/LEDE release, packages, etc.:
 - odhcpd version 2017-10-02-c6f3d5d4-2

Steps to reproduce:

Note: After a quick search on the internet I found out that more people are having this exact problem.

 1 - I installed a he.net tunnel with a /48 prefix
 2 - I configured the "lan" interfarce to assign itself a /56 prefix
 3 - I connected a router to the Ethernet port and let it ask for a prefix to the TP-link repeater
 4 - In the TP-Link repeater system logs you can see that the system has replyed about five or more times to the request but for some reason the devices never recognize it's response.


This is a log from a PFsense Router that asks for a prefix:

//__Note: It starts from the bottom up__//
