5.4.4.4. Important Things to Note when Ordering¶
Conditions
This menu provides services under a redundancy configuration (main/backup). Note that this menu is not available under a non-redundancy configuration.
The connection destination GCP information includes “availability zones of cites” to be designated as the main and backup ones. Also on the GCP side, application and redundancy control which meet them need to be performed.
Regarding application for Google Cloud Platform connections, the upper-limit and lower-limit numbers and the sales unit are as follows:
Maximum Number |
Minimum Number |

4 | 0 | 1 |
Preparation
Before applying for this menu, contract for use of the Google Cloud Platform(TM), and creation of cloud routers and partner interconnect attachments need to be carried out.
Create two cloud routers and two partner interconnect attachments for the purpose of redundancy.
When applying for through the customer portal/API, enter a “pairing key” ID issued when partner interconnect attachments are applied for.
Monitoring application status to the Google system
After start of opening processing on ECL2.0, activation status of the partner interconnect attachments in terms of the Google system is periodically monitored by ECL2.0. Note that, because of the specifications, GCP connection is automatically abolished when abolishment of either of the partner interconnect attachments is detected during monitoring.
Once opening processing is completed, periodical monitoring regarding the Google system is not performed by ECL2.0. If either or both of the partner interconnect attachments are deleted in this status, single side-use operations or communication disconnection result. Operations with the both side-use are assumed, so avoid to perform single side-use operations. If having deleted the partner interconnect attachments unintentionally after completion of the opening processing, abolish the corresponding lines and make an application again.
Regarding application during one-piece maintenance
There is a case where a part of new create / change / terminate can not be done during one-piece maintenance.
Depending on the content of maintenance, customer may not be able to apply for about a few days.
Please confirm that customers are connected redundantly after applying. Please refer to the tutorial for confirmation method.
Others
After newly applying for this menu, it can be canceled through the customer portal/API before activation with Google Cloud Console.
If a new application for this menu fails for any reason, the status before the application is restored. At that time, the partner interconnect attachments are abolished. Therefore, to make an application again, create partner interconnect attachments again and use a new pairing key.
This menu does not support operations of Google Cloud Console. Check with any GCP support (e.g., official documents).

5.4.7.3. SLA¶
The SLA for this Service Menu meets the SLA Standards defined by Enterprise Cloud 2.0.
This menu realizes 99.9 percent SLA provision only when main/backup redundancy has been applied for and the settings have been made properly.
5.4.7.4. Points to Note¶
Configuration
If multiple GCP gateways have been connected with the same logical network, communications fail due to the duplication of MAC addresses. Connect GCP gateways to different logical networks.
The MTU size in the GCP is 1,440 bytes. Set 1,440 bytes as the MTU size of the server which communicates with the GCP. If this setting is not made, communications may be disabled.
Do not connect to a logical network for common-function gateway connections. A link local address is allocated by Google as an IP address for the GCP connection segment, and thus address duplication can occur.
Operations
The sections other than the one to be connected regarding this menu are out of the support coverage. For failures (and others) regarding the section which Google LLC directly serves to the customer, notification by Service Provider will not be made.
Restrictions of communications to the GCP connection gateway
For communications to the GCP connection gateway, flow rate restriction is executed to protect the service platform.
For communications passing over the GCP connection gateway, flow rate restriction is not executed and the quality and rate based on the contracted plan are served.
