Command Example Fields Field IS-IS Level-1/Level-2 Link State Database LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT P OL Description Displays the IS-IS link state database for Level 1 or Level 2. 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. 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. This is the checksum of the entire LSP packet. 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. 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. This value represents the P bit. This bit will always set be zero as Dell Force10 does not support area partition repair. 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. show isis graceful-restart detail e Display detailed IS-IS Graceful Restart related settings.
