ASNs work similarlyto IP addresses that identifyindividual nodes on a network.Each ASN now consists of 32bits instead of 16 bits, andthey are assigned by IANA.autonomous system numberThe largest IP packet size inbytes allowable by routers ina path without fragmentationand excluding the frame size.MTU (maximum transmissionunit)A repeated trial messagetransmitted by the tracert andtraceroute utilities to triggerrouters along a route to returnspecific information about theroute.probeA router that connects anautonomous system with anoutside network—forexample, the router thatinterior router ListListSearchCreateLog inSign up
connects a business to itsISP.Properties of a route used byrouting protocols to determinethe best path to a destinationwhen various paths areavailable. Routing metricsmay be calculated using anyof several variables, includinghop count, bandwidth, delay,MTU, cost, and reliability.routing metricThe router on a network thataccepts all unroutablemessages from other routers.gateway of last resortThe delay between thetransmission of a signal andits receipt.latencyA process whereby routerslearn about all of the deviceson their networks. On IPv4networks, this process ismanaged by ARP with helpfrom ICMP. On IPv6 networks,NDP (Neighbor DiscoveryProtocol) automaticallydetects neighboring devicesand automatically adjustswhen nodes fail or areremoved from the network.neighbor discoveryA router that directs databetween networks within thesame autonomous system.gateway routerA number indicating aprotocol's reliability, with lowervalues being given higherpriority. This assignment canbe changed by a networkadministrator when oneprotocol should takeprecedence over a previouslyhigher-rated protocol on anetwork.
