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.
