When trying the same configuration in 9.0-RC1, rtadvd reports: Nov 13 18:19:31 g03 rtadvd[2818]: 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. >How-To-Repeat: Enable rtadvd using the following flags in rc.conf: rtadvd_enable="YES" rtadvd_interfaces="re1" >Fix: 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. >Release-Note: >Audit-Trail: >Unformatted:
