is-name

Function

The is-name command configures a dynamic hostname for a local device and enables it to identify the hostname carried in each LSP and advertise the configured dynamic hostname in LSPs.

The undo is-name command disables a local device from identifying the hostname carried in each LSP and deletes the configured hostname.

By default, no dynamic hostname is configured for the local IS-IS system.

Format

Usage Guidelines

Usage Scenario

In most cases, to check information about IS-IS neighbors and LSDBs on an IS-IS device, you need to use a system ID of a 12-digit hexadecimal number, for example, aaaa.eeee.1234. This representation, however, is complicated and not easy to use. The dynamic hostname mapping mechanism is introduced to facilitate maintenance and management of IS-IS networks. The is-name command is used to configure a simple hostname for a local device and enables the device to advertise it in an LSP.

After the configuration is completed, you can run the display isis name-table command to check the configured hostname.

Prerequisites

An IS-IS process has been created using the isis command in the system view.

Precautions

If a neighbor relationship has been established, running the is-name command will not cause the neighbor relationship to be reestablished or routes to be updated.

Example

# Configure the hostname for the local IS-IS system.
