Hi guys,
I upgraded my desktop at work just around christmas to 9-PRERELEASE builds
and ipv6 has been broken since then. I've been too busy at work to fix it
but today I finally had the chance to figure it out.
Currently I'm running:
12:11:15 tech304:~ > uname -a
FreeBSD tech304.office.supranet.net 9.0-STABLE FreeBSD 9.0-STABLE #2
r229703M: Fri Jan 6 11:01:58 CST 2012
root@tech304.office.supranet.net:/usr/obj/tank/svn/sys/GENERIC amd64
and my ipv6 is not working. In rc.conf I have
ipv6_enable_all_interfaces="YES" which sets the link local and I had
net.inet6.ip6.accept_rtadv=1 in sysctl.conf. I can confirm that it was
indeed activated in sysctl, but ifconfig didn't think so:
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC>
ether d0:67:e5:17:e1:32
inet6 fe80::d267:e5ff:fe17:e132%re0 prefixlen 64 scopeid 0x2
inet 192.168.93.23 netmask 0xffffff00 broadcast 192.168.93.255
nd6 options=23<PERFORMNUD,AUTO_LINKLOCAL> ## Where's the
ACCEPT_RTADV???
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
I have to manually do
# ifconfig re0 inet6 accept_rtadv
to get it to work. Am I missing something? Grepping /etc/rc.d/ for rtadv
finds no clues. Is this broken for everyone, for the re driver, or am I
just crazy?
Here's pciconf for the device -- let me know if any further info would be
useful:
re0@pci0:4:0:0: class=0x020000 card=0x04f51028 chip=0x816810ec rev=0x06
hdr=0x00
vendor = 'Realtek Semiconductor Co., Ltd.'
device = 'RTL8111/8168B PCI Express Gigabit Ethernet
controller'
class = network
subclass = ethernet
Thanks,
Mark

Do you have "inet6 accept_rtadv" keyword in it? IIRC it should be enough to specify ifconfig_re0_ipv6="inet6 accept_rtadv" without additional tweaks. Consult with rc.conf(5). HTH, pluknet

It is an unexpected behavior and the flag should be set on all interfaces.
