ABR – Area Border Router: A router that has interfaces in many OSPF areas. For more information on ABR, visit: Managing Routers.
ARP – Address Resolution Protocol: ARP finds a hardware address, also known as Media Access Control (MAC) address, of a host from its known IP address. It maintains a table in which MAC addresses are mapped to IP addresses. For more information on ARP, please visit: Configuring Address Resolution Protocol Options.
BGP – Border Gateway Protocol: Performs interdomain routing in TCP/IP networks. For more information on BGP, please visit: Border Gateway Protocol – Introduction.
CLI – Command-Line Interface: Cisco CLI The Cisco IOS command-line interface (CLI) is the primary user interface used for configuring, monitoring, and maintaining Cisco devices. It allows the user to directly and simply execute Cisco IOS commands, whether using a router console or terminal, or using remote access methods. For more information on CLI, please visit: Using the Cisco IOS Command-Line Interface documentation.
DHCP – Dynamic Host Control Protocol: enables users to dynamically and transparently assign reusable IP addresses to clients. For additional information on DHCP, please visit: Dynamic Host Control Protocol (DHCP)/Domain Name System (DNS) Introduction documentation.
DNS – Domain Name System: is the system in the Internet that maps names of objects (usually host names) into IP numbers or other resource record values. For additional information on DNS, please visit: Dynamic Host Control Protocol (DHCP)/Domain Name System (DNS) Introduction documentation.
OSPF – Open Shortest Path First: Open Shortest Path First (OSPF) is a routing protocol developed for the Internet Protocol (IP) . It uses a metric of link cost which adds the costs of each link cost from a router, to a subnet to determine the shortest path. For additional information on OSPF, please visit: Open Shortest Path First (OSPF) Introduction documentation.
