   IPv6 Prefix

      This field carries the IPv6 prefix to which the Segment ID is
      assigned.  In case of an Anycast Segment ID, this field will carry
      the IPv4 Anycast address.

   IPv6 Prefix

      This field carries the IPv6 prefix to which the Segment ID is
      assigned.  In case of an Anycast Segment ID, this field will carry
      the IPv6 Anycast address.

Notes
-----
Copy-pasta reusing the IPv4 IGP-Prefix Segment ID description for the IPv6 IGP-Prefix Segment ID description, and in the case of an IPv6 Anycast Segment ID it states that an IPv4 prefix should be entered into the IPv6 Prefix field.
