[Bridge] bridging ipv6

[Bridge] bridging ipv6

[filipe abrantes]

hello all:

im trying to set up a bridge for ipv6, but i cant manage to get it 
working, does someone have experience with this?

i used the common :

brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth2

then to set up the ip's i tried

ifconfig eth0 inet6 add ::/0
ifconfig eth2 inet6 add ::/0
ifconfig br0 inet6 add 2020::2/128

and also tried(the above didnt work for me):

removing all addresses from all bridged interfaces (even the link local 
ones).


Another question:

Is there any way i can set up a bridge and then block all level 2 
forwarding between the bridged interfaces?

I know it seems odd, but the idea was to have only one interface to 
handle the other two - its good for ipv6 multicasting,  that way you 
dont need to bind sockets to all interfaces.


thanks a lot

There is no point in using ipv6, here it is just enabling the
interfaces.
	ifconfig eth0 up
or	ifconfig eth0 0.0.0.0
does the same thing.

What is the state of eth0, eth2, and br0?
Does the bridge work for packets going through?
Can you ping anything?
What about doing a tcpdump on br0?

That is called bonding, use it instead of bridging.
