Re: Debugging SLAAC



Hello,

just recently I've had issues that SLAAC didn't worked out for a while
and started working again w/o knowing the reason.

I tried to sniff ICMPv6 packets, saw the RAs coming around every 5-6
minutes, but my net adapter didn't configured itself with a GUA derived
from the prefix in the RA.

Did you see Router Solicitation packets sent by the interface after the link was activated ?
Did the host set at least prefixes/routes from the RAs ?

What manages the interface ? Is SLAAC enabled for the interface in /proc/sys/net/ipv6/conf/ ?
Are NDP ICMPv6 packets allowed by the firewall rules ?

Is there any possiblitiy to increase the debug level to troubleshoot
issues with the address generation?

Checked dmesg, but didn't relveal much.

Did you see the message saying that no IPv6 routers were found ?
