ABR Area Border Router — a border router for an OSPF area. An ABR is
located on the border of one or more OSPF areas that connects those
areas to the backbone network. ABRs are treated as members of both
the OSPF backbone and the attached areas. They therefore maintain
routing tables that list both the backbone topology and the topology of
the other areas in the network.

ARP Address Resolution Protocol — ARP is a TCP/IP Interior Gateway
Protocol for dynamically mapping Internet addresses to physical
hardware addresses on LANs; limited to LANs that support hardware
broadcast.
ASBR Autonomous System Boundary Router — an area border router located
between an OSPF area and a non-OSPF network. As well as the OSPF
protocol, ASBRs run another routing protocol, such as RIP. ASBRs
cannot reside in a stub OSPF area.
autonomous system In Internet (TCP/IP) terminology, a series of gateways or routers that fall
