Creating SIM Target Route

This page explains how to create a SIM Target Route resource in a Virtual Mobile Gateway using the OCX Portal.

Preparation​

Please confirm the following before creating a SIM Target Route resource:

  1. Your User Role is either admin or user.
  2. The status of the target Virtual Mobile Gateway is activated.
  3. The target SIM belongs to an Address Pool of the target Virtual Mobile Gateway.

Remarks​

A SIM Target Route is a feature that delivers traffic destined for a specified IPv4 prefix to a specific SIM belonging to a Virtual Mobile Gateway.
It allows the OCX network, as well as devices with other SIMs in the same Virtual Mobile Gateway, to reach networks behind the device (such as a router) in which the SIM is inserted.

  • The registered IPv4 prefix is advertised from the Virtual Mobile Gateway to its BGP neighbors (OCX-Router(v1) or on-premises equipment (CPE)).
  • Traffic sent from the OCX network to the registered IPv4 prefix is delivered to the target SIM.
  • Traffic sent to the registered IPv4 prefix from another SIM in the same Virtual Mobile Gateway is also delivered to the target SIM. This traffic is turned around within the Virtual Mobile Gateway and does not pass through the OCX network side (OCX-Router(v1) or on-premises equipment (CPE)). This applies regardless of the Direct Device Communication setting.
  • Each SIM Target Route specifies one IPv4 prefix and one target SIM. You can create multiple SIM Target Routes with different IPv4 prefixes for the same SIM.
  • Traffic to the registered IPv4 prefix is not delivered while the target SIM is not connected to the mobile network.
  • A SIM that is the target of a SIM Target Route cannot be decommissioned (deleted). Decommission (delete) the SIM Target Route first.
  • There is a limit on the number of SIM Target Routes per Virtual Mobile Gateway. For details, please refer to Virtual Mobile Gateway Quotas.

The usable IPv4 prefix ranges are the private address ranges defined in RFC 1918:

  • 10.0.0.0/8
  • 172.16.0.0/12
  • 192.168.0.0/16

Specify the IPv4 prefix as a network address, with all host bits set to 0. (e.g., 192.168.10.0/24)
The prefix must not overlap with any of the following in the target Virtual Mobile Gateway:

  • IPv4 prefixes of Address Pools
  • Networks of the local and remote addresses of Instance 1 and Instance 2
  • IPv4 prefixes of existing SIM Target Routes (including those for other SIMs)

Procedure for Creating a SIM Target Route​

  1. Log in to the OCX Portal.
  2. Click [Access Lines] from the left navigation bar.
  3. When the [Access Lines] sub-menu appears, click [Virtual Mobile Gateways (VMGs)].
  4. From the Virtual Mobile Gateways page, click the target Virtual Mobile Gateway resource.
  5. The details panel will appear at the bottom of the screen. Switch to the SIM Target Routes tab and click the [Create SIM Target Route] button.
  6. The screen will switch to the SIM Target Route creation steps. Configure the following items and click [Create].
    • IPv4 Prefix
      • Enter the IPv4 prefix to be delivered to the target SIM in CIDR (IPv4/mask) format. (e.g., 192.168.10.0/24)
        *See [Remarks] for the available IPv4 prefixes.
    • SIM
      • Search for the target SIM by ID, ICCID or name, and select it.
      • IDs are matched exactly, ICCIDs by prefix, and names by partial match.
      • You can narrow down the displayed SIMs by Address Pool with [Filter by address pool].
  7. A creation confirmation pop-up will appear. Check the settings and click [Create].
  8. The SIM Target Route list will be displayed at the bottom of the screen, showing the created resource.
    Note: You can update the status by clicking [Refresh] in the upper right corner.

This completes the creation of the SIM Target Route resource.
