[Olsr-users] OLSR 0.6.8 on OpenWrt with ipv6 and kernel 3.18.x

[Henning Rogge]

Hi,

typically "detected duplicate packet with seqnr" happens if you either
have a problem with your linklayer driver OR a bad bridge
configuration.

Are "br-pub" and "ptp" somehow connected on one side or the other side
with a bridge?
