IRR Advice

Hi

So I am aware this is not a Mikrotik related question, I just wanted to see if anyone here had some advise.

We recently received our ASN and public IP block.

My question is, what are you supposed to do with IRR and object creation. I plan to peer in a few exchanges and with my upstream (s)

Could anyone give a simple, to the point, explanation of what objects are and why you create them. Sorry if this sounds like the dumbest question ever

Internet Routing Registries provide methods via which others can retrieve information relating to how IPs, ASNs and other resources are delegated. It allows others to, for example, query who is responsible for an IP or subnet and what prefixes are authorised to be announced by what ASN.

Your regional resource authority would most probably already have created organisational and person objects on your behalf, associated an inetnum object detailing the allocated range to your organisation and an ASN object. You typically only have to create a route object authorising a prefix to be valid when it originates from a specified ASN.

Herewith an example:

[root@backup1 ~]# whois 41.79.20.0/22                                                          % This is the AfriNIC Whois server.

You can additionally create as-set objects which assist upstream providers and peers in automating prefix administration. This eases administration, should you start acting as a transit provider for other networks. For example:

[root@backup1 ~]# bgpq3 -3 -l syrex-as path -f 37314 as-syrex
no ip as-path access-list syrex-aspath
ip as-path access-list syrex-aspath permit ^37314(_37314)*$
ip as-path access-list syrex-aspath permit ^37314(_[0-9]+)*_(7926|37316|327781|328074)$
ip as-path access-list syrex-aspath permit ^37314(_[0-9]+)*_(328086|328130|328144|328164)$

[root@backup1 ~]# bgpq3 -3Ab -l syrex-ipv4 -m 24 as-syrex
