Subject: looking for veth like.


Hi,
I need to inter-connect two bridges together.
I want to get this:


----------------                 ------------------


|       br0     |                 |         br1      |


----------------                 ------------------


   (veth0) ^                  ^ (veth1)


                 |___________|

So with my current kernel release (2.6.28-17), I used the virtual Ethernet pair device (veth) kernel module associated to the IP utility.

I did it as follows:

# First bridge
brclr addbr br0
ifconfig br0 up

# Second bridge
brctl addbr br1
ifconfig br1 up

# veth link
ip link add name veth0 type veth peer name veth1
ifconfig veth0 up
ifconfig veth1 up

# insertion
brctl addif br0 veth0
brctl addif br1 veth1

And for such kernel release it works fine.

But now I want to do so with an oldest kernel release (2.6.18-8 for instance).
This old release do not provide the virtual Ethernet pair device module.

Is there a way to  do the same with that oldest kernel release ? 
It there an veth-like module ? (I saw some stuffs suche as etun but can not get it... ?)

Thanks,
Christian.
