I don't like the strong ES model. IMHO, with weak ES model we can
obtain the best of multihoming benefits. the strong ES model
makes use of source routing, which might forbid the communication
where it could be possible.

I don't see why a host should discard a packet for him, only
because it has arrived at other interface.
