You have a few choices to achieve this. You can either disable the uniqueness constraint or use different VRFs to handle different prefixes and IP addresses. |

VRFs are what you need here. In Netbox, a VRF is both a layer 3 routing domain and a network namespace (i.e. domain of uniqueness for IP addresses). So even if you're not actually using multiple routing tables within the same network, and hence no actual VRFs, you can create a separate VRF for site A and site B, and put their respective prefixes and addresses within those VRFs, and they will not conflict. |
