Hello,
We're currently discussing necessity of multi-level hierarchy
in OSPF on the WG mail list.
The idea is to implement SPF-based interarea routing
with more than two levels of topology abstraction and
route aggregation (we have two levels in OSPF at the
moment level1 being intra-area routing and level2 being
the inter-area one).
I have some thoughts on how this could be done,
but the main question is whether there is a demand
for it or not.
Everyone is really welcome to share opinions.
Thanks in advance,
