What is benefit of allocating ASN to edge routers and not Ip addresses ? I mean we could have given these edge routers unique public ip addresses too ?

3I believe you are misinterpreting the article. All Internet devices have IP addresses -- that's how they communicate. AS Numbers are also used in the context of BGP protocol.– Ron TrunkAug 21 '19 at 11:52

2AS numbers are used by BGP, a routing protocol. Routing protocols do not route packets, they exchange routing information; packets are still routed by IP address.– Ron Maupin ♦Aug 21 '19 at 13:07

The answer provided by @Zac67 actually does that, and you should accept it.– Ron Maupin ♦Aug 21 '19 at 13:14

ASN numbers are assigned to corporate entities and don't ever change. IP routes are advertised under an ASN and can change at any time. Of course, devices participating in BGP require public IP addresses.
