Output fields are listed in the approximate order in which they appear.
—Complete sequence number PDUs contain a complete list of all link-state PDUs in the IS-IS
CSNP
database. CSNPs are sent periodically on all links, and the receiving systems use the information
in the CSNP to update and synchronize their link-state PDU databases. The designated router
multicasts CSNPs on broadcast links in place of sending explicit acknowledgments for each
link-state PDU.
—IS-IS hello packets are broadcast to discover the identity of neighboring IS-IS systems and to
IIH
determine whether the neighbors are Level 1 or Level 2 intermediate systems.
—Link-state PDUs contain information about the state of adjacencies to neighboring IS-IS
LSP
systems. Link-state PDUs are flooded periodically throughout an area.
—Partial sequence number PDUs are sent multicast by a receiver when it detects that it is
PSNP
missing a link-state PDU; that is, when its link-state PDU database is out of date. The receiver sends
a PSNP to the system that transmitted the CSNP, effectively requesting that the missing link-state
PDU be transmitted. That routing device, in turn, forwards the missing link-state PDU to the
requesting routing device.
—The PDU type is unknown.
