AS Number management

As ...

Nelly - Network Engineer

I want ...

to be able to manage assignment of public and private autonomous system numbers

So that ...

I can easily reference what ASN's are assigned and where they are assigned, and who (RIR or private entity) assigned them.

I know this is done when...

• There is data model for AS numbers in Nautobot, that links to RIRs and sites.
• ASNs can be listed, searched and created from the web interface or API
• The AS Number field is updated to a foreign key to this new data model
• The migration takes care of converting the ASN field on a site to a new ASN entry in that model
• I can request the next free ASN from a specific block (e.g. private ASNs) (Credit to @sirtux )

Optional - Feature groups this request pertains to.

• [ ] Automation
• [ ] Circuits
• [ ] DCIM
• [X] IPAM
• [ ] Misc (including Data Sources)
• [ ] Organization
• [ ] Plugins (and other Extensibility)
• [ ] Security (Secrets, etc)
• [ ] Image Management
• [X] UI/UX
• [ ] Documentation
• [ ] Other (not directly a platform feature)

Database Changes

New model for AS Numbers

• ASN (16 or 32 byte values)
• Allocating RIR (Nullable)
• Description
• Custom fields or config contexts?

Thanks, I've added that to the wishlist!

Im currently working on implementing this and currently considering the relationship between sites and ASNs. In Netbox this is modeled as a Many-to-Many relationship.

Any opinions on this?

[achard]

For my purposes a one-to-one field would work, but many to many has more flexibility for broader use cases. I think that makes sense.

In my opinion, a ASN should have many-to-many relationships to any object. Some people might want to have one or more ASN mapped to a site, I have a ASN per device in IP-Fabrics, and even ASNs per Interface (e.g. Core Router towards the internet have the public ASN, towards the fabric a private one).

If we at a later stage have BGP sessions in nautobot, it might even be per session than...

Moving this over to the nautobot-bgp app backlog.
