Table: Output fields: router IS-IS database

Label

Description

LSP ID

Displays the LSP ID

LSP IDs are auto-assigned by the originating IS-IS node. The LSP ID is comprised of three sections. The first 6 bytes is the system ID for that node, followed by a single byte value for the pseudonode generated by that router, and a fragment byte which starts at zero.

For example, if a router system ID is 1800.0000.0029, the first LSP ID is 1800.0000.0029.00-00. If there are too many routes, LSP ID 1800.0000.0029.00-01 is created to contain the excess routes. If the router is the Designated Intermediate System (DIS) on a broadcast network, a pseudo-node LSP is created. Usually the internal circuit ID is used to determine the ID assigned to the pseudonode. For instance, for circuit 4, an LSP pseudonode with ID 1800.0000.0029.04-00 is created.

The router learns hostnames and uses the hostname in place of the system ID. An example of LDP IDs are:

acc_arl.00-00

acc_arl.00-01

acc_arl.04-00

Sequence

Displays the sequence number of the LSP that allows other systems to determine whether they have received the latest information from the source

Checksum

Displays the checksum of the entire LSP packet

Lifetime

Displays the amount of time, in seconds, that the LSP remains valid.

Attributes

OV — The overload bit is set

L1 — Specifies a Level 1 IS type

L2 — Specifies a Level 2 IS type

ATT — The attach bit is set. When this bit is set, the router can also act as a Level 2 router and can reach other areas

LSP Count

Displays the sum of all the configured Level 1 and Level 2 LSPs.

LSP ID

Displays a unique identifier for each LSP composed of SysID, Pseudonode ID, and LSP name

Lifetime

Displays the remaining time until the LSP expires

Version

Displays the version/protocol ID extension. This value is always set to 1.

Pkt Type

Displays the PDU type number

Pkt Ver

Displays the version/protocol ID extension. This value is always set to 1.

Max Area

Displays the maximum number of area addresses supported

Sys ID Len

Displays the length of the system ID field (0 or 6 for 6 digits)

Use Len

Displays the actual length of the PDU

Alloc Len

Displays the amount of memory space allocated for the LSP

Area Address

Displays the area addresses to which the router is connected

Supp Protocols

Displays the data protocols that are supported

IS-Hostname

Displays the name of the router originating the LSP

Virtual Flag

0 — Level 1 intermediate systems report this octet as 0 to all neighbors

1 — Indicates that the path to a neighbor is a Level 2 virtual path used to repair an area partition

Neighbor

Displays the routers running interfaces to which the router is connected

Internal Reach

Displays a 32-bit metric. A bit is added for the ups and downs resulting from Level 2 to Level 1 route-leaking.

IP Prefix

Displays the IP addresses that the router knows about by externally-originated interfaces

Metrics

Displays a routing metric used in the IS-IS link-state calculation

hostname

Syntax

hostname

Context

show>router>isis

Platforms

Supported on all 7210 SAS platforms as described in this document
