FreeBSD g03.rpsol.net 9.0-RC1 FreeBSD 9.0-RC1 #0: Tue Oct 18 18:30:38 UTC 2011 root at obrian.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
In FreeBSD 8.2-RELEASE, rtadvd is working properly, and clients are receiving IPv6 addresses. When trying the same configuration in 9.0-RC1, rtadvd reports:
Nov 13 18:19:31 g03 rtadvd: non-zero lifetime RA on RA receiving interface re1. Ignored.
At this point, rtadvd fails to advertise IPv6 addresses to clients. After reading the man page, it looked like passing the -s flag to rtadvd would suppress this behavior, but that had no effect.
To test, I commented out the block of code in /usr/src/usr.sbin/rtadvd/rtadvd.c that handled this, recompiled and installed, and rtadvd works as it did in FreeBSD 8.2-RELEASE.
Enable rtadvd using the following flags in rc.conf:
Lines 1701 through 1724 were commented out in /usr/src/usr.sbin/rtadvd/rtadvd.c. rtadvd was recompiled and installed, then started, which resumed operation as it existed in 8.2-RELEASE.
