On-premises IDC reference configuration

Configuration examples for on-premises data centers with BGP

This topic provides the configuration examples for switches (such as Huawei and H3C) at the on-premises data center (IDC) side when using BGP routes.

tip

These examples are for reference only, providing a configuration approach. Please adapt the instructions to your specific operational environment.

​
# Optional: Configure routes learned from VolcanoEngine on the on-premises IDC side. Only learn large segments of routes published by VolcanoEngine and reject detailed routes.​
# For example: The on-premises IDC can learn routes from Volcano Engine such as 10.0.0.0/8, 10.1.0.1/32, and 10.2.0.2/32. After configuring the rejection of specific routes, the on-premises IDC will only learn the route 10.0.0.0/8.​

# Example: The local IDC can learn routes 10.0.0.0/8, 10.1.0.1/32, and 10.2.0.2/32 from VolcanoEngine. After configuring the rejection of specific routes, the local IDC will only learn the route 10.0.0.0/8.​
