Re: OT: Sub-Area support in OSPF?

AFAIK this is not implemented by both Cisco and Juniper. I also wonder what advantage this would give above normal areas. It does give a little advantage for MPLS TE, but with a later Draft-RFC this is solved by delegating control over the area to a specified ABR (a loose next-hop) and inter-area TE is supported on both Cisco and Juniper.
