Loosing prefix after valid-lft expires. #47

Closed 4mig4 closed 5 years ago

4mig4 commented 8 years ago

Hi, Using LEDE or OpenWRT trunk odhcp6c somehow lets the valid-lifetime of interface expire and the prefix if the quite logically getting dropped from the interface.

This has been tested on several types of interfaces ethernet copper , SFP modules , GEPON ONU SFP and various versions of OpenWRT and LEDE all resulting in the same loss of prefix.

There were other problems related to that but odhcp6c still looks like it is not doing the right thing, however to fix issues like #46 this will help:

echo 0 > /sys/devices/virtual/net/br-lan/bridge/multicast_snooping

Ok the problem is still there, the prefix gets lots on a regular basis. It would be good if Steven could look into that because looking at the code I have many questions that are unanswered.
