I have just been using rtsol to see what changes. I have these in my rc.conf. Let me verify = some of these things on my other 12.2 box so I can give better info in terms of = RA. I'm using pfSense and to my understanding it's using RA. ifconfig_re0_ipv6=3D"inet6 accept_rtadv" ipv6_activate_all_interfaces=3D"YES" Note the behavior is no different whether I have rtsold enabled and running= or not I can restart netif and get an IPv6 address without rtsol so I assume my interface is listening for RAs? > what is the output of "ndp -r" closer to the route expiration? How does "= ndp -p" look?
