See maximum transmission unit (MTU) (page 79).
mu-law
Normally written as m-law. A technique for translating pulse code modulated
voice into 64 kbit/s digital voice channels. m-law is used in North America,
Japan, and other countries that use DS-1 function processors. See also
A-law

multicast border router (MBR)
A router that participates in more than one multicast domain.
multicast domain
A set of one or more contiguous links with optional routers that implement the
same multicast protocol configured to operate within a common boundary.
multicast forwarding

multi-hop BGP
Multi-hop border gateway protocol (BGP) refers to a BGP connection
established between peers that are not directly connected and can span
across multiple hops. See also
external border gateway protocol (EBGP)

multilink frame relay (MLFR)
A service for FrUni and FrNni connections. MLFR provides physical interface
emulation for frame relay devices. The emulated physical interface consists of
one or more DS1 links, called bundle links, that are aggregated into a single
bundle that offers greatly expanded bandwidth. This service also provides a
frame-based inverse multiplexing function, sometimes referred to as a inverse
multiplexing for frame relay (IMUX). This definition is in accordance with the
Frame Relay Forum Implementation Agreement FRF.16.
