Topic: OpenWrt/CC device with static ipv6 i/f can't ping ipv6 router

The content of this topic has been archived on 21 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

The ipv6 router sends neighbor adverts, but my openwrt device never sends router solicitations. When I ping from openwrt device to router, there are continuous neighbor solicits/adverts, but addr resolution is failing:

# ip -6 neigh show
fd7c:564f:c6f2:f682::99 dev eth1  FAILED

I've tried with ip6gw set and unset. 

My interface config:

config interface 'vlan3_v6'
        option ifname 'eth1'
        option proto 'static'
        option hostname 'mydna'
        option metric '1'
        option description 'unittestinterface IPv6'
        option role 'external'
        option force_link '1'
        option ip6addr 'fd7c:564f:c6f2:f682::100/64'
        option ipv6 '1'

# ifconfig eth1

Is there any other info that I can/should provide?

The discussion might have continued from here.
