      SR is enabled globally, and the Segment Routing view is displayed.

   3. Run commit

      The configuration is committed.

   4. Run quit

      Return to the system view.

   1. Run ospf [ process-id ]

      The OSPF view is displayed.

   2. Run opaque-capability enable

      The Opaque LSA capability is enabled.

   3. Run segment-routing mpls

      OSPF SR is enabled.

   4. Run segment-routing global-block begin-value end-value [ ignore-conflict ]

      An OSPF SRGB is specified.

      If a label in the SRGB range to be specified is in use, you can select the ignore-conflict parameter to allow configuration delivery. However, the configuration does not take effect until the device is restarted and the label is released. In normal cases, specifying ignore-conflict is not recommended.

   2. Run ospf enable [ process-id ] area area-id

      OSPF is enabled on the interface.

   3. Run ip address ip-address { mask | mask-length }

   4. Run ospf prefix-sid { absolute sid-value | index index-value } [ node-disable ]

      An SR prefix SID is configured for the IP address of the loopback interface.
