Dear Editors,
I think that wording of chapter 3.3 Flooding Scope can use some
refinement. Currently it reads:
" The flooding scope for PCE information advertised through OSPF can
be
limited to one or more OSPF areas the PCE belongs to, or can be
extended across the entire OSPF routing domain.
Note that some PCEs may belong to multiple areas, in which case the
flooding scope may comprise these areas. This could be the case for
an ABR for instance advertising its PCE information within the
backbone area and/or a subset of its attached IGP area(s). "
But the scope of OSPFv2 or OSPFv3 Router Information LSA can be either
an Area or Autonomous System, but it can not be several areas. If PCED TLV
needs to be flooded through some but not all areas, the proper Router
Information LSA must be originated by the PCE into each area.
Yes, the ABR can generate a type 10 Router Info LSA in each target area.
And here I have a question - would PCED TLV MUST be the same in all
areas or it MAY be different?
They may differ.
Regards,
JL
Regards,
Greg
