multihomed AS
An AS that has multiple connections to one or
more ASs and does not carry transit traffic.
Multicast Link Discovery (MLD)
An asymmetric protocol. MLD specifies separate
behaviors for multicast address listeners and
multicast routers.
multicast router discovery (MRDISC)
Provides the automatic discovery of multicast
capable routers. By listening to multicast router
discovery messages, Layer 2 devices can
determine where to send multicast source
data and Internet Group Management Protocol
(IGMP) host membership reports.
Multicast Router Discovery Protocol (MRDP)
Discovers multicast routers in a Layer 2 bridged
domain configured for IGMP snooping.
Multicast Router Learning Protocol (MRLP)
Provides basic information between two core
switches, for example, neighbor information
learning for edge switches, messages that
determine the forwarder, and multicast tree
building information related to the edge switch.
MultiLink Trunking (MLT)
A method of link aggregation that uses multiple
Ethernet trunks aggregated to provide a single
logical trunk. A multilink trunk provides the
combined bandwidth of multiple links and the
physical layer protection against the failure of a
single link.
multimode fiber (MMF)
A fiber with a core diameter larger than the
wavelength of light transmitted that allows
many modes of light to propagate. Commonly
used with LED sources for low speed and short
distance lengths. Typical core sizes (measured
in microns) are 50/125, 62.5/125 and 100/140.
