Note: For more IS-IS-related commands, such as show route protocol, show route instance, and show route table, see Protocol-Independent Routing Operational Mode Commands. For information about monitoring Bidirectional Forwarding Detection (BFD) sessions for IS-IS clients, see BFD Operational Mode Commands. For information about how to configure IS-IS, see the JUNOS Routing Protocols Configuration Guide.

Note: In IS-IS command output, the CLI displays the system ID numerically by default. To display the hostname instead, include the static-host-mapping statement at the [edit system] hierarchy level of the configuration.
