This is factually incorrect. It's uncommon but legitimate practice to employ a private AS number which is dropped from the path by your upstream provider. > Replace > “1.

It's difficult for me to understand how any router implementing something more complex than a default gateway has not implemented a routing policy unique to its network. "Multihomed" I understand. It just means you have two or more ISPs at the same time. > 1. “Sites that do not require a unique AS Number should use one or more of > the AS Numbers reserved for private use.” Some customers are not aware that > their need for a unique AS Number depends upon their need (or lack thereof) > to utilize the AS Number on the public Internet. This is not entirely accurate. Any multi-organization internetwork using the BGP protocol requires coordination of AS numbers no different than they need coordination of IP addresses. It's not just the public Internet. > 3. “AS Numbers are issued based on current need.

Additionally, clarification that some organizations may have a unique > need for an AS Number outside of utilizing a unique routing policy, such as > BGP. Can't we just be rid of justified needs analysis for AS numbers? What exactly is the objective of preventing someone who thinks they want an AS number from getting one? There aren't really any scarcity issues and having or lacking an AS number doesn't particularly change one's ability to introduce routes into the public BGP table. -- William Herrin [email protected] https://bill.herrin.us/ _______________________________________________ ARIN-PPML You are receiving this message because you are subscribed to the ARIN Public Policy Mailing List ([email protected]).
