Cross-reference BGP ASN and Devices

[dmulyalin]

NetBox version

v4.1.3

Feature type

Data model extension

Proposed functionality

BGP ASN rarely exist on its own and in most of the cases assigned to or used by devices, Netbox as of now does not have capability to capture what devices use what ASNs without relying on custom fields, adding multiref field to device to link ASNs it is using can help to improve Netbox ASN documentation capabilities.

Use case

Devices use ASN but currently Netbox does not have built in way to establish relationship between BGP ASN and devices apart from using custom fields, this use case is to introduce such a relationship and help network operators document what ASNs used by what devices.

Database changes

Device model need to be extended with asns many-to-many field with relevant UI additions.

External dependencies

What specifically are you proposing? Assigning an ASN directly to a device would not suffice for moderately complex routing policies which advertise different AS numbers to different peers. IMO this falls entirely within the scope of BGP routing policy.

I am proposing to link devices with ASNs similar to how we link device interfaces with VLANs, since ASNs used by devices and it is important to capture what devices use what ASN for various use cases - configuration rendering, network audit, troubleshooting to name a few.
