Hi, I've just found a mistake in the text.
* An increase of Autonomous systems might not have as big of effect on hardware requirements as one might think at first. Conservation measures for cases presented in RFC1930 and *RFC2280 *and others conserve only the AS number, and do not conserve the processing power and memory needed to process the announced prefixes. When a foreign prefix (e.g. PI) as announced (via e.g. private ASN) from an AS (e.g. ISP) it still creates a separate entry in the routing table.
Instead, I've meant RFC2270.
