Creating IS-IS Processes

Creating IS-IS Processes

Context

Creating IS-IS processes is the prerequisite for performing IS-IS configurations.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ] [ vpn-instance vpn-instance-name ]

    An IS-IS process is created, and the IS-IS process view is displayed.

    The process-id parameter specifies the ID of an IS-IS process. If the process-id is not specified, by default, the value of process-id is 1. To associate the IS-IS process with a VPN instance, specify the VPN instance name.

  3. (Optional) Run description description

    Description for the IS-IS process is configured.

  4. (Optional) Enable IS-IS to add the POI and hostname TLV to Purge LSPs.

    Run purge-originator-identification enable [ always ]

    IS-IS is enabled to determine whether to add the POI TLV and hostname TLV to Purge LSPs based on the authentication configuration.

    • If the purge-originator-identification enable command is run and any authentication is configured, generated Purge LSPs do not carry the POI TLV or hostname TLV.

    • If the purge-originator-identification enable command is run and no authentication is configured, generated Purge LSPs carry the POI TLV or hostname TLV.

    • If the purge-originator-identification enable always command is run, generated Purge LSPs carry the POI TLV and hostname TLV, regardless of whether authentication is configured.

  5. (Optional) Disable automatic IS-IS system ID recovery in case of conflicts.

    Run isis system-id auto-recover disable

    Automatic IS-IS system ID recovery is disabled in case of conflicts.
