LSPID

The rst six octets are the System ID of the originating router.
The rst 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 oods 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 t 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
state database. A value between brackets indicates the duration that the purged
LSP stays in the database before being removed.
