Channel Bonding : questions again

Hello !

Me again about bonding. :-)

Does anyone know if :

- it's possible to have a physical interface (for ex : eth0) part of many
bonding groups ?
ie eth0 is slave of bond0 and also slave of bond1 for example
- if a bond interface can be a slave of another bond interface ?
ie bond0 is slave of bond1 for example

My tests showed that's it's not possible but I wanted to be sure, maybe I
missed something.

Thanks four your answers.

I can't think of how either of these could be possible, but then, I
don't currently have an environment to test. Could you describe a set-up
where these features would make sense - what would be the read-world
application for this functionality?

I don't have any idea actually, it was just to know, cause I'm studying
Channel Bonding and want to know the most about that.

Thanks for your answer.

If you consider (in the abstract sense) what bonding is/does, that should
somewhat bring up the possible structures (which seem to be very simple).
So, bonding is just a way to provide some resilience against component
failures, and provide better aggregate bandwidth between two Ethernet
devices.

What I've been thinking to look at, but unfortunately haven't had the
chance yet, is whether VLANs work ok over bonded interfaces.
