Configuring Multilink Frame Relay
Multilink Frame Relay (MFR) is a cost-effective bandwidth solution that is based on Frame Relay Forum Multilink Frame Relay UNI/NNI Implementation Agreement (FRF.16.1). This feature increases bandwidth by bundling multiple physical links into a logical link.
MFR uses the following concepts:
Bundle—A virtual interface formed by combining multiple physical interfaces. A bundle corresponds to an MFR interface. A bundle is visible to the data link layer.
Bundle link—Corresponds to a physical interface. A bundle contains and manages multiple bundle links, as shown in Figure 53. Bundle links are visible to the physical layer.

MFR interfaces support DTE and DCE interface types and QoS queuing mechanisms. Physical interfaces bundled into an MFR interface use the data link and network parameter settings of the MFR interface. Their original parameters settings do not work.
