Example Field LSP Checksum LSP Holdtime ATT P OL Description 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 is always set to 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 do not use this system as a transit router when calculating routes. The bold sections identify that Multi-Topology IS-IS is enabled.
