Thanks for the pointer.

Does that mean that it is impossible to announce a route on some interfaces
only? It looks like a rather arbitrary limitation.

In case I misunderstood and it is actually possible, I fail to see ĥow the
alternating algorithm takes this into account: it seems to assume that a node
will accept to route any packet on any interface. Did I miss something?
