Dear Mr. Wayrynen,
Thank you very much for your reply. What do you mean by "unnumbered interfaces"? Also could you please confirm my question that if the customer's address block was not obtained from the provider, it is also a convention that the provider will provider the /30 address for the inter-domain link?
From the replys, it seems to me that there is no way to tell which link is indeed the inter-domain link, if the two ASes are peers. But for customer-providers, I can guess with confidence. Could I get these information from the IPSes' or PoP's website, about who are their customers/peers? And how exactly the addresses were assigned?
Sincerely
Teng
