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