    Junos Space IPv6 Support Overview

    Starting from Junos Space Network Management Platform Release 14.1R2, you can discover and manage devices by using IPv6 addresses. Junos Space Platform supports the management of devices configured with only IPv4 addresses, only IPv6 addresses, or both. In addition, Junos Space Platform receives traps for IPv6 devices by using IPv6 addresses.

    You can also configure IPv6 addresses for the following IP addresses:

    • Virtual IP (VIP) address of the Junos Space fabric
    • Node management and device management IP addresses of Junos Space nodes
    • Administrative interface (eth1) for Junos Space nodes
    • Default gateway IP address for Junos Space nodes
    • VIP address of the Fault Monitoring and Performance Monitoring (FMPM) nodes
    • Node management IP address of FMPM nodes
    • Default gateway IP address for Junos Space and FMPM nodes

    Note: If you configure IPv6 addresses for any of the preceding IP addresses, you must also configure an IPv4 address. Junos Space Platform does not allow you to configure only IPv6 addresses for Ethernet interfaces of fabric nodes. Table 1 displays the IP address configurations supported on Junos Space Platform.

    Devices managed by Junos Space Platform can initiate connections by using an IPv4 or IPv6 address. When Junos Space Platform initiates the connection to a device, the type of connection (IPv4 or IPv6) depends on the type of IP address specified during device discovery.

    Note: For non-SRX Series devices, device-initiated connections to Junos Space Platform that use IPv6 addresses are supported only on Junos OS Release 15.1 or later; this is because IPv6 addresses are supported in the outbound-SSH configuration only from Junos OS Release 15.1 onward for non-SRX Series devices. For SRX Series devices, device-initiated connections to Junos Space Platform that use IPv6 addresses are supported from Junos OS Release 12.1x47D15 onward.

    You can also modify the target IP address of a device (from IPv4 to IPv6, IPv4 to IPv4, IPv6 to IPv4, and IPv6 to IPv6), which Junos Space Platform uses to connect to a device. For more information, see Modifying the Target IP Address of a Device.

    Note: The following limitations are applicable when you use IPv6 addresses:

    • IPv6 support for devices depends on the version of Junos OS running on the device; earlier versions of Junos OS might not support IPv6 configuration. IPv6 support for device-initiated connections is available from Junos OS Release 15.1R1 onward.
    • All nodes in the Junos Space fabric must have the same type of IP address (or addresses) configured. For example, if a Junos Space node or an FMPM node in a fabric is configured with both IPv4 and IPv6 addresses, then all other Junos Space and FMPM nodes in the fabric must be configured with both IPv4 and IPv6 addresses.
