Display Message
LSPID:
The LSP identifier. The first six octets form the system ID of the router that originated the
LSP.
LSP Seq Num:
Sequence number for the LSP that allows other systems to determine if
they have received the latest information from the source.
LSP Checksum:
Checksum of the entire LSP packet.
LSP Holdtime:
Amount of time the LSP remains valid (in seconds). An LSP hold time of zero
indicates that this LSP was purged and is being removed from the link-state database (LSDB) of all
routers. The value indicates how long the purged LSP will stay in the LSDB before being completely
removed.
ATT
: The Attach bit. This bit indicates that the router is also a Level 2 router, and it can reach other
areas. Level 1-only routers and Level 1-2 routers that have lost connection to other Level 2 routers
will use the Attach bit to find the closest Level 2 router. They will point a default route to the closest
Level 2 router.
Area Address:
Reachable area addresses from the router. For Level 1 LSPs, these are the area
addresses configured manually on the originating router. For Level 2 LSPs, these are all the area
addresses for the area to which this route belongs.
Metric:
IS-IS metric for the cost of the adjacency between the originating router and the advertised
neighbor, or the metric of the cost to get from the advertising router to the advertised destination
