display isis lsdb

Function

The display isis lsdb command displays the LSDB information of IS-IS.

Format

display isis lsdb [ verbose [ no-name ] | { level-1 | level-2 } | { local | lspid | is-name isname } ] * [ process-id | { vpn-instance vpn-instance-name } ]

display isis process-id lsdb [ { level-1 | level-2 } | verbose [ no-name ] | { is-name isname | local | lspid } ] *

Parameters

Parameter Description Value
verbose

Displays detailed information about the LSDB.

-
no-name

Displays detailed information about the LSDB, without the alias information.

-
level-1

Displays information about the Level-1 LSDB.

-
level-2

Displays information about the Level-2 LSDB.

-
local

Displays information about the local LSDB.

-
lspid

Specifies an LSP ID.

The value is in dotted decimal notation, ranging from 16 to 20 and in the format of ####.####.####.##-##, such as 0050.0500.5004.00-00.
is-name isname

Specifies a dynamic hostname.

The value is a string and it has two values:

  • symbolic-name: the length is from 1 to 64.
  • symbolic-name.XX-XX: the length is from 1 to 70.

When quotation marks are used around the string, spaces are allowed in the string.
process-id

Specifies an IS-IS process ID.

The value is an integer ranging from 1 to 4294967295.
vpn-instance vpn-instance-name

Specifies the VPN instance to which an IS-IS process belongs.

The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

To view the LSDB information of IS-IS, run the display isis lsdb command. If no level is specified, information about Level-1 and Level-2 LSDBs is displayed.

If verbose is specified, you can view detailed information about the IS-IS LSDB, including the multi-topology (MT) ID, MT neighbor ID, and IPv6 prefix.

Example

The actual command output varies according to the device. The command output here is only an example.

INTF ADDR

IP addresses of interfaces.
INTF ADDR V6

IPv6 addresses of interfaces.
+IP-Extended

Extended IPv4 routing information, which carries TE-related information.
Total LSP(s)

Total number of LSPs.
*(In TLV)

Leaked route.
*(By LSPID)

Self-LSP, which is generated by the local device.
Bier-SD

BIER sub-domain.
Max SI

Max SI.
BS Len

Bit String Length.
IPV6

Information about internal IPv6 routes.
Adj-Sid

P2P neighbor SID.
NBR ID

System ID of a neighbor.
Prefix-Sid

Prefix label.
Router Cap

Device capability information.
Flexible Algorithm Cap

Flexible algorithm capability information.
Algorithm

Prefix label flag:
Segment Routing Cap

Segment routing capability information.
Segment Routing IPv6 Cap

Information about IPv6 segment routing capabilities.
Segment Routing MSD

Maximum SRv6 SID depth.
SRGB Base

Start value of SRGB.
SRv6 Locator

SRv6 locator TLV information.
SRv6 End Sid

SRv6 SID value.
Holdtime

Redistribute List

Redistribute List.
Flag

Flag of the prefix label.

  • R: indicates the penetration flag. If R is set, it indicates that the prefix SID is leaked between levels or imported from other protocols.
  • N: indicates the node label. When N is set, it indicates that the prefix corresponding to the Prefix-Sid can identify the device and is a node label.
  • P: indicates the no-PHP flag. When the P flag is set to 1, it indicates that the label cannot be popped out on the penultimate hop.
  • E: indicates an explicit null label. If E is set, the penultimate hop must use an explicit null label to replace the actual label.
  • V: value flag. When V is set, it indicates that the Prefix-Sid corresponds to an absolute label value instead of an offset value.
  • L: indicates the local flag. When L is set, it indicates that the prefix SID has a local flag.
D

Direction of re-advertisement. Value 1 indicates that the IS-IS Router Capability TLV in a Level-2 area is shared with a Level-1 area.
S

Flood flag:

  • 0: The IS-IS Router Capability TLV is not flooded between level-specific areas.
  • 1: The IS-IS Router Capability TLV is flooded within a whole domain.
Range

SRGB range.
COST

Route cost.
Function
