Example YAML Code:

Example-1: Configure Segment Routing v6 with multiple locators.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        segment_routing_v6:
          enable: true
          encapsulation_source_address: "fccc:0:214::1"
          locators:
            - name: "Locator1"
              locator_enable: true
              micro_segment_behavior: "unode-psp-usd"
              prefix: "fccc:0:214::"
              prefix_length: 48
            - name: "Locator2"
              locator_enable: true
              micro_segment_behavior: "unode-psp-usd"
              prefix: "fccc:0:215::"
              prefix_length: 48

Example-2: Configure Segment Routing v6 with single locator.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        segment_routing_v6:
          enable: true
          encapsulation_source_address: "fccc:0:300::1"
          locators:
            - name: "MainLocator"
              locator_enable: true
              micro_segment_behavior: "unode-psp-usd"
              prefix: "fccc:0:300::"
              prefix_length: 48

Example-3: Configure Segment Routing v6 with format and uSID configuration.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        segment_routing_v6:
          enable: true
          encapsulation_source_address: "fccc:0:400::1"
          formats:
            - name: "usid-f3216"
              usid_local_id_block_ranges_lib_start: 57344
              usid_local_id_block_ranges_explict_lib_start: 57444
              usid_wide_local_id_block_explicit_range: 65520
          locators:
            - name: "uSID_Locator"
              locator_enable: true
              micro_segment_behavior: "unode-psp-usd"
              prefix: "fccc:0:400::"
              prefix_length: 48
