Which statement describes the creation of LSAs by ABRs in the discontinuous network situation?

Which statement describes the creation of LSAs by ABRs in the discontinuous network situation?

• Type 3 LSAs received from Area 0 are created for nonbackbone areas.
• Type 1 LSAs received from nonbackbone areas are forwarded into the backbone area.
• Type 3 LSAs received from a nonbackbone area are created in other nonbackbone areas.
• Type 1 LSAs received by the ABR are forwarded into other nonbackbone areas.

Explanation: There are three fundamental rules that ABRs use for creating type 3 LSAs:

• Type 1 LSAs received from an area create type 3 LSAs into the backbone area and nonbackbone areas.
• Type 3 LSAs received from Area 0 are created for the nonbackbone area.
• Type 3 LSAs received from a nonbackbone area only insert into the LSDB for the source area. ABRs do not create a type 3 LSA for the other areas (including a segmented Area 0).
