Benefits
- Provides stable connectivity to SaaS and IaaS, and optimizes network traffic.
- Simplifies configuration by centralizing BGP settings on the OCX-Router (v1).
- Enhances communication redundancy to SaaS and IaaS by implementing an East-West (Tokyo-Osaka) redundant configuration.
Notes
- Ensure that AS numbers and network segments do not overlap in your design.
- For terms and conditions regarding the use of each service, please contact the respective service provider.
- A separate connection to DNS is required (e.g., via internet connection or private DNS).
- An East-West redundant configuration is required to meet the SLA standards for XaaS Connection. For SLA applicability of each service, please refer to the Overview of XaaS Connection.
- Some services may be out of SLA scope or may not support East-West redundant configurations.
- The recommended session limit per NAT IP address is approximately 62,000 sessions.
- If the number of sessions increases, consider adding additional NAT IP addresses.
