Radvd Woes...

[Admiral]

Hi ,

Suddenly overnight my ipv6 stopped working. Wireshark on client shows me : No router advertisements are being sent, radvd is running.
I've stopped radvd to run it manually from cli. No router advertisements are being sent to the lan , except to itself.
I've set the Route lifetime to 30 secs to debug , rtr min  : 3 , max to 4

I adjusted some igmp-related settings on my switch in the meantime : It works again , but .. i didn't touch that switch-config in weeks .
I've adjusted MLD v1 -> v2 and tadaa.. :/
