FreeBSD, problem setting up rtsol/rtadvd
![[ch]](/s/countries/ch.gif) Shadow Hawkins on Tuesday, 30 December 2008 14:39:13
I am having problems setting up rtsol/rtadvd with FreeBSD. I got the following subnet assigned:
2001:41e0:ff62::/48
Gateway:
OS: FreeBSD i386 7.0-RELEASE (PC-Engines)
ifconfig:
# ifconfig -a
vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=280b<RXCSUM,TXCSUM,VLAN_MTU,WOL_UCAST,WOL_MAGIC>
ether 00:0d:b9:14:ea:28
inet 192.168.1.16 netmask 0xffffff00 broadcast 192.168.1.255

ether 00:0d:b9:14:ea:29
inet 77.57.221.162 netmask 0xfffff000 broadcast 255.255.255.255

gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280
tunnel inet 77.57.221.162 --> 194.1.163.40
inet6 2001:41e0:ff00:ba::2 --> 2001:41e0:ff00:ba::1 prefixlen 128
/etc/rtadvd.conf:
vr0:\
:addrs#1:addr="2001:41e0:ff62::":prefixlen#64:
As you can see I assigned 2001:41e0:ff62::1 to vr0, the internal interface. rtadvd is up and running.
Now I try to assing an IP to a host behind the gateway:
Client:
OS: FreeBSD 7.0 (amd64)
Kernel options:
net.inet6.ip6.accept_rtadv=1
net.inet6.ip6.forwarding=0
Now I'm trying to assing an address to interface re0 with rtsol:
# rtsol -D re0
checking if re0 is ready...
get_llflag() failed, anyway I'll try
set timer for re0 to 0:24967
New timer is 0:00024735
New timer is 0:00000387
New timer is 0:00000283
New timer is 0:00000216
New timer is 0:00000151
New timer is 0:00000087
New timer is 0:00000026
timer expiration on re0, state = 1
send RS on re0, whose state is 2
sendmsg on re0: Can't assign requested address
set timer for re0 to 4:0
New timer is 4:00000326
timer expiration on re0, state = 2
send RS on re0, whose state is 2
sendmsg on re0: Can't assign requested address
set timer for re0 to 4:0
New timer is 4:00000352
timer expiration on re0, state = 2
send RS on re0, whose state is 2
sendmsg on re0: Can't assign requested address
set timer for re0 to 1:0
New timer is 1:00000348
timer expiration on re0, state = 2
No answer after sending 3 RSs
stop timer for re0
there is no timer
Maybe I don't see the obvious. Any help would be great.

Can you post /etc/rc.d?

Oops, make that /etc/rc.conf

That's on the gateway:

It seems to me that you need an ipv6_enable="YES" on your "host behind the gateway"
Can you post ifconfig -a from the "host behind the gateway"?
Do you have any other hosts that are trying to receive an auto-config address from this router? Are there any errors related to rtadvd in /var/log/messages?
FWIW, this is the content of my /etc/rtadvd.conf
cat /etc/rtadvd.conf
fxp0:\
:addrs#1:addr="2001:4978:1d8:f000::":prefixlen#64:tc=ether:

That was the problem. After setting ipv6_enable="YES" and restarting the host the interface was properly configured.
Thanks Carl.
