Please refer to the second part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection Network view, the process required to use the best possible path. No user data passed during convergence. failure domain ( fault domain ) ----- area of the failed token ring. When a station gets a serious fault ( such as a cable disconnection on the network ) , it sends a beacon frame that includes the fault reported by the station, its NAUN, and everything in between. This defines the fault domain. The beacon then begins the so-called automatic configuration process. See autore compression ( compression ) with a string of numerals repeated data, transmitted over a link than the normal grant 0x2142 bypasses the process of loading startup-config , or : does not load the boot configuration , directly enter the setup mode 0x2102 router default configuration key value , perform the normal boot sequence . The basis of word expression. The number of hops added to a particular network,ine ccie security v5 topology, which converges slowly. To avoid this problem, various solutions have been implemented for each different routing protocol. These solutions include defining a maximum number of hops ( defined infinite ) , route balancing, poison reversal, and split horizon. Use more than one metric to find the best path to a remote network. By default, both IGRP and EIGRP use the bandwidth and latency of the line.
