An AS provides a structured view of routing by " "segregating the system that is using routing (e.g., the " "Internet, or an extranet) into a set of separately " "administered domains that each have their own independent " "routing policies. These domains are called autonomous systems.\n" "\n" "The classic definition of an AS, from RFC1771, is '...a set of " "routers under a single technical administration, using an " "interior gateway protocol and common metrics to route packets " "within the AS, and using an exterior gateway protocol to route " "packets to other ASs'. The RFC continues: 'Since this classic " "definition was developed, it has become common for a single AS " "to use several interior gateway protocols and sometimes " "several sets of metrics within an AS. The use of the term " "Autonomous System here stresses the fact that, even when " "multiple IGPs and metrics are used, the administration of an " "AS appears to other ASs to have a single coherent interior " "routing plan and presents a consistent picture of what " "destinations are reachable through it.'") ] class CIM_AutonomousSystem : CIM_AdminDomain { [Description ( "An ASNumber is an integer between 1 and 65535, with the " "range 64512 through 65535 reserved for private use.
