   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.
