1Full support for VMware available starting with SBC 8.1.

2Supported for four packet port configuration only. Not supported for any other packet port configuration.

3The SBC Core SWe/Cloud on AWS and GCP does not support IPv6. However, AWS infrastructure supports IPv6 and GCP does not support IPv6.



Feature Limitations of SBC in GCP Compared to SBC in AWS

The SBC in GCP includes the following limitations when compared to the feature set for the SBC running in AWS:

  • Multiple IPs for traffic segregation is not possible because of the limitations with the number of EIPs you can assign per NIC interface.

  • Subnet gateways in the GCP are virtual. You cannot use them for Link Detection on the SBC, as they do not respond, resulting in continuous switchovers.

    Note

    For Link Detection configurations of HFE instances in GCP, provide any communicable IP address between the HFE and SBC. Ribbon recommends providing nic2 IP addresses for HFE 2.1, and nic3 and nic4 IP addresses for HFE 2.0.

  • To use a bastion server for SBC in GCP to access the management interface using private IP addresses, you must create the server in a subnet separate to the management interface.

  • Logical Management IP addresses are not supported by SBC in GCP.
