--An address used temporarily by a mobile node as a tunnel exit-point when the mobile node is connected to a foreign link.
--A router on a visited network of a mobile node that provides routing services to the mobile node while registered. The foreign agent detunnels and delivers datagrams to the mobile node that were tunneled by the home agent of the mobile node. For datagrams sent by a mobile node, the foreign agent may serve as a default router for registered mobile nodes.
--A router on the home network of a mobile node that tunnels packets to the mobile node while it is away from home. It keeps current location information for registered mobile nodes called a mobility binding.
--An SNMP trap message that includes a delivery confirmation request. See "trap."
--Management Information Base. Database of network management information that is used and maintained by a network management protocol such as SNMP. The value of a MIB object can be changed or retrieved using SNMP commands, usually through a Network Management System (NMS). MIB objects are organized in a tree structure that includes public (standard) and private (proprietary) branches.
--A host or router that changes its point of attachment from one network or subnet to another. A mobile node may change its location without changing its IP address; it may continue to communicate with other Internet nodes at any location using its home IP address, assuming link-layer connectivity to a point of attachment is available.
--network management system. An application or suite of applications designed to monitor networks using SNMP. CiscoView is one example of an NMS.
--Simple Network Management Protocol. Management protocol used almost exclusively in TCP/IP networks. SNMP provides a means to monitor and control network devices, and to manage configurations, statistics collection, performance, and security, typically through the use of an NMS.
--security parameter index. The index identifying a security context between a pair of nodes.
--Message sent by an SNMP agent to a network management station, console, or terminal to indicate the occurrence of a significant event, such as a specifically defined condition or a threshold that was reached.
