A tunnel that uses static LSPs to forward packets to the destination. This phrase is often used in the
LSP tunnel/MPLS
TE tunnel abstract sense, with emphasis on the fact that the tunnel is using an LSP to forward data, but without
emphasis on the implementation of the tunnel itself.
label switch router. The role of an LSR is to forward packets in an MPLS network by looking only at
LSR
the fixed-length label.
M
Standardized data link layer address that is required for every port or device that connects to a LAN. Other
MAC address
devices in the network use these addresses to locate specific ports in the network and to create and update
routing tables and data structures. MAC addresses are 6 bytes long and are controlled by the IEEE. Also
known as a hardware address, MAC layer address, and physical address. See also MAC.
Pattern of bits used to reject or accept bit patterns in another set of data.
mask
minimum boot image. Software image containing kernel and minimum set of drivers and components
MBI
to boot up a node.
megabits per second. A bit rate expressed in millions of binary bits per second. 1 megabit = 2
Mbps
1,048,576 bits.
Management Data APIs.
MDA
multi exit discriminator. BGP metric that provides information to external neighbors about the
MED
preferred path into an autonomous system.
The forwarding engine that performs ingress and egress packet processing and forwarding decisions.
metro
Management Information Base. Database of network management information that is used and
MIB
maintained by a network management protocol like Simple Network Management Protocol (SNMP).
The value of an MIB object can be changed or retrieved using SNMP commands, usually through a GUI
network management system. MIB objects are organized in a tree structure that includes public
(standard) and private (proprietary) branches.
Multicast OSPF. Intradomain multicast routing protocol used in OSPF networks. Extensions are
MOSPF
applied to the base OSPF unicast protocol to support IP multicast routing.
Multiprotocol Label Switching. Switching method that forwards IP traffic using a label. This label
MPLS
instructs the routers and the switches in the network where to forward the packets based on
preestablished IP routing information
Multiprotocol Label Switching traffic engineering. A switching method that forwards IP traffic using
MPLS TE
a label. This label instructs the routers and the switches in the network where to forward the packets
based on preestablished IP routing information.
