Aging
When an entry for a node is added to the lookup table of a switch, it is given a timestamp. Each time a packet
is received from a node, the timestamp is updated. The switch has a user-configurable timer that erases the
entry after a certain length of time with no activity from that node.
Area Border Router
A router located on the border of one or more OSPF areas that connects those areas to the backbone
network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore
maintain routing tables describing both the backbone topology and the topology of the other areas. (Cisco
