Software Installation and Upgrade

  • Support for DHCPv6 on zero-touch provisioning (ZTP) (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.2R1, ZTP supports the DHCPv6 client on management and WAN interfaces. During the bootstrap process, the device first uses the DHCPv4 client to request information regarding image and configuration files from the DHCP server. The device checks the DHCPv4 bindings sequentially. If one of the DHCPv4 bindings fails, the device continues to check for bindings until provisioning is successful. If no DHCPv4 bindings exist, however, the device checks for DHCPv6 bindings and follows the same process as for DHCPv4 until the device can be provisioned successfully. The DHCP server uses DHCPv6 options 59 and 17 and applicable sub-options to exchange ZTP-related information between itself and the DHCP client.
