Hi All,
IPv4 Routing -
------------------------
I disabled the DHCP from rc.conf for both the interface. but still I am not
able to route trafic from one interface to another.

rc.conf
---------------
hostname="idc-freebsd"
keymap="hy.armscii-8.kbd"
#ifconfig_re0="DHCP"
#ifconfig_rl0="DHCP"
dumpdev="NO"
ifconfig_rl0="inet 192.168.100.101 netmask 255.255.255.0
ifconfig_re0="inet 192.168.200.101 netmask 255.255.255.0
ipv6_activate_all_interfaces="YES"
gateway_enable="YES"
default_router="192.168.200.1"

I am using FreeBSD - 9.1 Release version

I need to communicate between two different subnets.

Am i missing anything to enable freebsd as router?
Do i need to add a route entry?

If possible could you please share rc.conf file with IPv4 routing?

Regards
Hrisikesh

Are the two lines above copied straight from your rc.conf file?
If so, both lines are missing a " at the end. Please check to see if
this is needed.

Next, the outputs of the ifconfig command and the netstat -r command
should reveal something interesting. Would you please post the
results from these two commands?

Neither NIC is connected to any equipment, e.g. switch, hub, or
computer (status: no carrier). Make sure you can use a straight
network cable, else you'll need to get a couple of cross wired network
cables and use those instead.

Next, confirm the sysctl net.inet.ip.forwarding is set to 1 by
running the sysctl net.inet.ip.forwarding command.

If not, you can set the sysctl to 1 by running the sysctl
net.inet.ip.forwarding=1 command, and you probably should inspect the
/etc/rc.conf file one more time.

Once you connect the computer to the two networks, the IPv4 routing
should work. If not, come back.

Hi Trond ,
Thanks a lot.
Now i am able to ping to other network with IPv4 address.

For IPv6 I added these lines in rc.conf -
first I included -
ipv6_gateway_enable="YES"

++> Laptop1( Ipv6 address fe80::224:7eff:fee0:6b51) is connected to
interface rl0 ( ipv6 address - fe80::21f:b5ff:fe48:9f73)
While doing ping6 from "fe80::224:7eff:fee0:6b51" to
"fe80::21f:b5ff:fe48:9f73" - it is working. Neighbor advertisement from
"fe80::21f:b5ff:fe48:9f73" is happening.
while doing from ping6 from "fe80::224:7eff:fee0:6b51" to other interface
"fe80::21f:d0ff:fe40:8bbd" , then there is no Neighbor advertisement.

After this I included these two lines to rc.conf -

rtadvd_enable="YES"
rtadvd_interfaces="rl0"

I have not created any file like /etc/rtadvd.conf . Do i need to create
this configuration file?
if yes, what should be the input to rtadvd.conf for link local address?

please find Ipv6 interface details.

Congratz on achieving active carrier wave on your NICs.

Right now your system is running with link-local IPv6 addresses. You
may view LL addresses as VLAN local. Packets to such addresses will
never ever be forwarded by a router.

Instead set up either official IPv6 addresses/subnets or create your
own Unique Local Addresses (ULA) as I wrote previously about.

Augment your /etc/rc.conf file with, say:

ifconfig_rl0_ipv6="inet6 fd8f:d6d0:e6e7:100::101 prefixlen 64"

You may assign the IPv6 address manually to avoid restarting the
networking subsystem or the whole machine:

ifconfig rl0 inet6 fd8f:d6d0:e6e7:100::101 prefixlen 64

Next, create /etc/rtadvd.conf with the following contents:

rl0:\
:addr="fd8f:d6d0:e6e7:100::":prefixlen#64:

If you want IPv6 routing on the re0 interface, you need, say this, in
/etc/rc.conf:

ifconfig_re0_ipv6="inet6 fd44:13de:a366:200::1 prefixlen 64"

Assign the IPv6 address manually using:

ifconfig re0 inet6 fd44:13de:a366:200::1 prefixlen 64

And add this to /etc/rtadvd.conf:

re0:\
:addr="fd44:13de:a366:200::":prefixlen#64:

You'll need to restart rtadvd by issuing /etc/rc.d/rtadvd restart.

Happy hacking.

Hi Trond,
Thanks a lot for a clear reply.
Could you please tell me Laptop1 ipv6 configuration details?
as laptop auto configuration will generate the LL address for a auto ipv6
configuration.
For Interface rl0 ipv6 address
ifconfig_rl0_ipv6="inet6 fd8f:d6d0:e6e7:100::101 prefixlen 64" ,

what will be laptop ipv6 address?

It depends solely on the operating system and whether IPv6 privacy is
in effect.

Normally, the client will perform stateless automatic address
configuration (SLAAC). It goes pretty much like this:

The router announces the 64 bit prefix, usually every 200 seconds, but
the client may request a new announcement at any time. The client
generates a 64 bit interface identifier based on its 48 bit MAC
address. The client then concatenates the supplied prefix with the
generated interface identifier. The client then performs duplicate
address detection (DAD), and if everythings checks out, the client got
its IPv6 address.

Given this prefix fd8f:d6d0:e6e7:100::/64, and this MAC address
50:e5:49:41:4d:70.

The client would then generated this interface id:
52e5:49ff:fe41:4d70.

The Universal/Local bit of the MAC address is inverted, and FF:FE is
placed at center. (It really ought to be FF:FF, but way back in time
someone misread the IEEE standards regarding conversion from 48 bit
MAC addresses to EUI64 format. This oversight doesn't really matter.)

The same client would then aqcuire this IPv6 address:
fd8f:d6d0:e6e7:100:52e5:49ff:fe41:4d70, and perform DAD.

The client gets its IPv6 default route/gateway from the router
announcement.

Of course, you may configure the IPv6 address and gateway manually on
the client, say fd8f:d6d0:e6e7:100::1337/64 (client's address) and
fd8f:d6d0:e6e7:100::101 (gateway's address).

Hi Trond,
Thanks a lot for your help and Ipv6 routing is working with FreeBSD OS.
we want to go for Ipv6 certification for our IPv6 stack.
And Ipv6 stack we want to use FreeBSD as one vendor router.

Now It will be easy for IPv6 interoperability test with freeBSD.

for Ipv6 interoperability test We need another router device and I am
planning use Ubuntu as IPv6 router.

Please let me your personal view and if you can help me on this, it will be
grateful.

Hmm. I'm not at all familiar with Ubuntu or any other Linux distro for
that matter. I admit, I did try out Debian/amd64 7.0.0 a couple of
weeks ago, but I have far more experience with FreeBSD than anything
else in the *nix world.

Truth to be told, I regard most Linux distros as inferior compared to
the *BSDs, due to the Linux distros forcing you to install a whole lot
of bloat. It probably boils down to what level you are on, be it Joe
Public or someone with more experience when it comes to computers and
operating systems. Maybe I'm just misinformed and there exists a Linux
distro or two letting the user/administrator chose what to install
rather well.
