Multilink Frame Relay

VERVIEW
MLFR is defined in FRF 16.1. It is an extension to the Frame Relay Protocol. See
"Frame Relay"
of the multilink concept, refer to
MLFR C
OMPONENTS
A typical MLFR configuration has at least two components:
•
A bundle interface
•
An interface running Frame Relay is made multilink-enabled and attached to the
bundle interface.

PERATION
After the bundle interface is configured and an interface running Frame Relay is
made multilink enabled, bundle and link identifiers are configured appropriately.
This results in the transmission of appropriate Link Integrity Protocol messages on
the bundle link. Once the bundle link state machine reaches the UP state, normal
Frame Relay Link Management (LMI) procedures are started over the bundle.
This means the LMI packets can be sent over any of the associated bundle links
as they are all going to the same peer. After LMI comes up, the line protocol is
said to be up on the bundle and if IP addresses have been configured at both
ends of the bundle, IP packets can be sent over the bundle.
The MLFR packet is encapsulated using an MLFR header, which is different from
the standard Frame Relay header. It contains a sequence number and also allows
for fragmentation/reassembly of the MLFR packet.
MLFR is also referred to as MFR.
