Field Description
IS-IS Level-1/
Level-2 Link
State Database
Displays the IS-IS link state database for Level 1 or Level 2.
LSPID
Displays the LSP identifier.
The first six octets are the System ID of the originating router.
The first six octets are the System ID of the originating router. The next octet is
the pseudonode ID. If this byte is not zero, the LSP describes system links. If this
byte is zero (0), the LSP describes the state of the originating router.
The designated router for a LAN creates and floods a pseudonode LSP and
describes the attached systems.
The last octet is the LSP number. An LSP is divided into multiple LSP fragments if
there is more data than cannot fit in a single LSP. Each fragment has a unique LSP
number.
An * after the LSPID indicates that the system originates an LSP where this
command was issued.
LSP Seq Num This value is the sequence number for the LSP that allows other systems to
determine if they have received the latest information from the source.
LSP Checksum This is the checksum of the entire LSP packet.
LSP Holdtime This value is the amount of time, in seconds, that the LSP remains valid. A zero
holdtime indicates that this is a purged LSP and is being removed from the link
