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.
The function and configuration of the MFR interface is the same with that on the
FR interface in common sense. Like the FR interface, the MFR interface supports
DTE and DCE interface types as well as QoS queue mechanism. After physical
interfaces are bundled into an MFR interface, their original network layer and
frame relay link layer parameters become ineffective and they use the parameter
settings of the MFR interface instead.
Follow these steps to configure multilink frame relay:
To do...
Enter system view
Create MFR interface and
enter the MFR interface view
Configure MFR bundle
identifier
Enable MFR fragmentation
Set the size of MFR sliding
window
Configure the maximum
fragment size for the bundle
link
Configure other parameters
of the MFR interface
Return to system view
Enter specified interface view interface interface-type
Bundle the current interface
to an MFR interface
Use the command...
system-view
interface mfr
{ interface-number |
interface-number.subnu
mber }
mfr bundle-name
[ name ]
mfr fragment
mfr window-size
number
mfr fragment-size

Remarks
-
Required
MFR interface or subinterface is not
created by default.
Optional
The bundle identifier is "mfr +
frame relay bundle number" by
default. This identifier only has only
significance.
In spite of the default BID, you
cannot configure a BID as a string
in the form of mfr + number.
Optional
Fragmentation is disabled on MFR
bundles by default.
Optional
The size of MFR sliding window is
equal to the number of physical
interfaces bundled by MFR by
default.
Optional
The maximum fragment is of 300
bytes by default.

Required
An interface is not bundled with
any MFR interface by default.
