EGP exchanges reachability information between autonomous systems. An autonomous system is usually defined as a set of routers under a single administration, using an interior gateway protocol and common metric to route packets.
Autonomous systems use exterior routing protocols to route packets to other autonomous systems.
Like EGP, BGP exchanges reachability information between autonomous systems, but supports nonhierarchical topologies. BGP uses path attributes to provide more information about each route. Path attributes can include, for example, administrative preferences based on political, organizational, or security considerations. This protocol is used to inform hosts of the availability of hosts it can send packets to and is used to supplement a statically configured default router. UNIX Utility Function ifconfig Configures or displays network interface parameters, redefines an address for a particular interface, or sets options such as an alias list, broadcast address, or access filter.
