Multilink Frame Relay
Overview
Overview
Multilink Frame Relay (MFR for short) is a kind of bandwidth solution with higher
performance-price ratio provided for frame relay users. Based on the FRF.16
protocol of frame relay forum, it implements MFR function on UNI/NNI interfaces.

MFR feature provides a kind of logic interface, namely MFR interface, which is
compound of multiple frame relay physical links bound together, so as to provide
high-speed and broadband links on frame relay networks.

In order to maximize the bandwidth of bundled interface, it is suggested to bundle
physical interfaces of the same rate for the same MFR interface upon configuring
the MFR interface so as to reduce management labor.

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. Bundle manages its
bundle links. The interrelationship between bundle and bundle link is illustrated as
follows:

MFR interface and physical interface
An MFR interface is a kind of logic interface. Multiple physical interfaces can be
bundled into one MFR interface. One MFR interface corresponds to one bundle
and one physical interface corresponds to one bundle link. The configuration on a
bundle and bundle links is actually configuration on an MFR interface and physical
interfaces.
bundled into one MFR interface. One MFR interface corresponds to one bundle
and one physical interface corresponds to one bundle link. The configuration on a
bundle and bundle links is actually configuration on an MFR interface and physical
interfaces.
The function and configuration of an MFR interface is the same with that on an FR
interface in common sense. It also supports DTE and DCE interface types as well as
QoS queue mechanism. After physical interface are bundled into an MFR
interface, the originally configured parameters on network layer and frame relay
link layer will no longer work. Parameters on this MFR interface will be used
instead.
