SNMP—Simple Network Management Protocol. Network 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. See also SNMP2.

SNMP2—SNMP Version 2. Version 2 of the popular network management protocol. SNMP2 supports
centralized as well as distributed network management strategies, and includes improvements in the
SMI, protocol operations, management architecture, and security. See also SNMP.

traffic engineering—The techniques and processes used to cause routed traffic to travel through the
network on a path other than the one that would have been chosen if standard routing methods had been
used.
network on a path other than the one that would have been chosen if standard routing methods had been
used.
trap—A message sent by an SNMP agent to a network management station, console, or terminal,
indicating that a significant event occurred. Traps (notifications) are less reliable than inform requests,
because the receiver does not send an acknowledgment when it receives a trap. The sender cannot
determine if the trap was received. See also notification.

VPN—Virtual Private Network. A group of sites that, as the result of a set of administrative policies, are
able to communicate with each other over a shared backbone network. See MPLS VPN.

VPN ID—A mechanism that identifies a VPN based on RFC 2685. A VPN ID consists of an
Organizational Unique Identifier (OUI), a three-octet hex number assigned by the IEEE Registration
Authority, and a VPN index, a four-octet hex number, which identifies the VPN within the company.

VRF—VPN routing/forwarding instance. A VRF consists of an IP routing table, a derived forwarding
table, a set of interfaces that use the forwarding table, and a set of rules and routing protocols that
determine what goes into the forwarding table. In general, a VRF includes the routing information that
defines a customer VPN site that is attached to a PE router.
