This looks to me like a good idea.
It does not require a separate management network.
A small flooding topology would be a spanning tree.
This would assume that upon a link failure, both ends of a p2p link detect the failure and send an LSA within an acceptable time.
If not, then I would add a second link to any nodes that have only one link in the spanning tree.

Thanks,
Jakob

> Abstract:
>   Routing with link state protocols in dense network topologies can
>   result in sub-optimal convergence times due to the overhead
>   associated with flooding.  This can be addressed by decreasing the
>   flooding topology so that it is less dense.
