Multilink frame relay (MFR) is a cost effective bandwidth solution for frame relay
users. Based on the FRF.16 protocol of the frame relay forum, it implements MFR
function on DTE/DCE interfaces.
MFR function provides a kind of logic interface, namely MFR interface. The MFR
interface is composed of multiple frame relay physical links bound together, so as
to provide high-speed and broadband links on frame relay networks.
To maximize the bandwidth of bundled interface, it is recommended to bundle
physical interfaces of the same rate for the same MFR interface when configuring
the MFR interface so as to reduce management cost.
Bundle and bundle link
Bundle and bundle link are two basic concepts related to MFR.
One MFR interface corresponds to one bundle, which may contain multiple bundle
links. One bundle link corresponds to one physical interface. A bundle manages its
bundle links. The interrelationship between bundle and bundle link is illustrated as
follows:

For the actual physical layer, bundle link is visible; while for the actual data link
layer, bundle is visible.
