Originally created by @m0nkeyc0de on 2/9/2026

NetBox version

v4.5.2

Feature type

Data model extension

Proposed functionality

Allow to set two (or more) VRFs to an IP Prefix.

Use case

VRFs aren't isolated networks. At some point they interconnect with another routing domain (or VRF) which has its own routing table. This other routing domain could also be managed by the same network administrator.

To document this reality in Netbox, we can create VRF A and VRF B. But the interconnection Prefix (which exists in the routing table as "locally connected" in both VRFs) can only be assigned to a single VRF, which makes the documentation inaccurate.

Database changes

Add a vrfs ManyToMany field on ipam.models.ip.Prefix and migrate current vrf Field into it.
