Hi Robert and misc@openbsd, thanks for your reply, but if i don't want to connect area 12 on area 0 ? My area 12 is reserved for LAN to LAN only, i don't want to publish its routes on the backbone area and backbone area is not in stub mode.
Also, I thought about stub areas to not publish routes. I think i must apply stub to area 3 but not under area 12, right ? Stub is on the area on which we don't want to obtain routes from other areas, don't we ?
