The is-name map command enables the local switch to identify the host name in LSPs, and sets a static host name for a remote IS-IS system on the local switch.
The undo is-name map command disables the local switch from identifying the host name in LSPs, and deletes the static host name for a remote IS-IS system set by the local switch.
By default, the local device does not have the static host name of a remote IS-IS system.
| Parameter | Description | Value |
|---|---|---|
system-id |
Specifies the ID of the remote mapped IS-IS system or pseudonode ID. |
The format is XXXX.XXXX.XXXX[.XX]. |
symbolic-name |
Specifies the static host name of the remote mapped IS-IS system. |
The value is a string of 1 to 64 characters without spaces. It is case sensitive. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
When checking information about IS-IS neighbors and LSDBs on the switch that runs IS-IS, each switch in the IS-IS routing domain is represented by a system ID with a 12-bit hexadecimal number, for example, aaaa.eeee.1234. This representation is complicated and not easy to use. To manage and maintain IS-IS networks conveniently, IS-IS uses the dynamic host name exchange mechanism. The is-name map command can configure a host name for the remote switch and does not advertise the host name through an LSP.
After running the is-name map command to map the remote switch to the host name, you can find that the system ID of the remote switch is replaced by the host name configured using the display isis name-table command.
Precautions
This configuration is static configuration and takes effect only on the local device. Therefore, the configured host name symbolic-name is not advertised through an LSP. If dynamic host name mapping is configured on an IS-IS device, dynamic host name mapping takes precedence over static host name mapping.
