With a simple check of a routing table, network operators can determine the source and target ASes and all transit ASes through which the packet moves on its way to the destination.
BGP AS PATH Attribute for Network Path VisibilityīGP routing information provides full Internet path visibility. This is one of the attributes that is evaluated in the BGP best path selection process. The set of ASes along the path between two Autonomous Systems on the Internet is called BGP AS_PATH. Each AS is represented by a unique number called an AS number (ASN). An AS can be an ISP, a university or the entire corporate network. BGP’s role is to exchange routing and reachability information between autonomous systems (ASes) on the Internet.
Border Gateway Protocol (BGP) is a core routing protocol used by most of the Internet Service Providers (ISPs).
