Table 65 show isis database verbose Field Descriptions 

Field
Description

LSPID

LSP identifier. The first six octets form the System ID of the router that originated the LSP.

The next octet is the pseudonode ID. When this byte is zero, the LSP describes links from the system. When it is nonzero, the LSP is a pseudonode LSP. This is similar to a router LSA in OSPF; the LSP describes the state of the originating router. For each LAN, the designated router for that LAN creates and floods a pseudonode LSP that describes all systems attached to that LAN.

The last octet is the LSP number. If all the data cannot fit into a single LSP, the LSP is divided into multiple LSP fragments. Each fragment has a different LSP number. An asterisk (*) indicates that the system issuing this command originated the LSP.

LSP Seq Num

LSP sequence number that allows other systems to determine if they received the latest information from the source.

LSP Checksum

Checksum of the entire LSP packet.

LSP Holdtime

Amount of time that the LSP remains valid (in seconds). An LSP hold time of zero indicates that this LSP was purged and is being removed from all routers' link-state databases (LSDBs). The value indicates how long the purged LSP will stay in the LSDB before it is completely removed.

ATT

Attach bit. This bit indicates that the router is also a Level 2 router, and it can reach other areas. Level 1 routers use the Attach bit to find the closest Level 2 router. They install a default route to the closest Level 2 router.

P

P bit. This bit detects if the IS can repair area partitions. Cisco and other vendors do not support area partition repair.

OL

Overload bit. This bit determines if the IS is congested. If the overload bit is set, other routers do not use this system as a transit router when they calculate routes. Only packets for destinations directly connected to the overloaded router are sent to this 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 router belongs.

NLPID

Network Layer Protocol identifier.

Hostname

Host name of the node.

Router ID

Traffic engineering router identifier for the node.

IP Address

IPv4 address for the interface.

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 (which can be an IP address, an end system (ES), or a connectionless network service (CLNS) prefix).

Affinity

Link attribute flags that are being flooded.

Physical BW

Link bandwidth capacity (in bits per second).

Reservable BW

Amount of reservable bandwidth on this link.

BW Unreserved

Amount of bandwidth that is available for reservation.
