Creating IS-IS Processes

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, the value of process-id is 1 by default. To associate the IS-IS process with a VPN instance, specify the VPN instance name.

3. (Optional) Run descriptiondescription

   A description is configured for the IS-IS process.

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 the send-only parameter is specified when configuring authentication, generated Purge LSPs do not carry the POI TLV or hostname TLV.

   • If the purge-originator-identification enable command is run and MD5 or HMAC-MD5 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 authentication of another type is configured or no authentication is configured, generated Purge LSPs carry the POI TLV and 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 or whether the send-only parameter is specified when configuring authentication.
