  • 1—Intermediate system routes within an area; when the destination is outside an area, it routes toward a Level 2 system.
  • 2—Intermediate system routes between areas and toward other ASs.

All levels

LSP ID

Link-state PDU identifier.

All levels

Sequence

Sequence number of the link-state PDU.
