display isis traffic-eng advertisements

Function

The display isis traffic-eng advertisements command displays Traffic Engineering (TE) information advertised the last time.

Format

display isis traffic-eng advertisements [ local | lspId ] [ level-1 | level-2 | level-1-2 ] [ process-id | { vpn-instance vpn-instance-name } ]

display isis process-id traffic-eng advertisements [ local | lspId ] [ level-1 | level-2 | level-1-2 ]

Parameters

Parameter	Description	Value
local	Displays TE information advertised by the local router.	-
lspId	Displays TE information carried in the LSP with a specified 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.
level-1	Displays TE information in a Level-1 link state database (LSDB).	-
level-2	Displays TE information in a Level-2 link state database (LSDB).	-
level-1-2	Displays TE information in Level-1 and Level-2 link state database (LSDB).	-
process-id	Specifies the ID of an IS-IS process.	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 TE information advertised the last time, run the display isis traffic-eng advertisements command.

When the level-1-2 keyword is used in the command, displays TE information in a Level-1 or Level-2 LSDB according to the type of the local node. That is, if the local node is a Level-1 or Level-2 node, TE information in a Level-1 or Level-2 LSDB is displayed. If the local node is a Level-1-2 node, TE information in Level-1 and Level-2 LSDBs is displayed.

If you do not specify level-1 or level-2, TE information in both Level-1 and Level-2 LSDBs is displayed.

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