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 next octet is the pseudonode ID. If this byte is not zero, then the LSP
describes system links. If this byte is zero (0), then 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 will be 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 an LSP was originated by the system 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.
ATT This value represents the Attach bit. This indicates that the router is a Level 2
router and can reach other areas. Level 1-only routers and Level 1-2 routers that
have lost connection to other Level 2 routers use the Attach bit to find the
closest Level 2 router. They point a default route to the closest Level 2 router.
P This value represents the P bit. This bit will always set be zero as Dell Force10
does not support area partition repair.
OL This value represents the overload bit, determining congestion. If the overload
bit is set, other routers will not use this system as a transit router when
calculating routes.
