Re: OSPF : LSA

Wow, nice to know.

You state that <area 0> to <other area> route propagation is done via
redistribution, and so the route has to be in the RIB "owned by" OSPF to
be inserted in some non 0 area.

The other way around, from <other area> to <area 0>, follows some
internal mechanism so it's RIB independant.

Thanks,
