Creating an MFR
Interface
Perform the following in the System View.
By default, no MFR interface or sub-interface is created.
Before creating the MFR sub-interface, MFR main interface must have existed
already; otherwise, the creation will not succeed.
already; otherwise, the creation will not succeed.
When deleting an MFR interface, first delete all real physical interfaces bundled on
the interface.
the interface.
For an MFR interface, as long as one of the physical interfaces bundled on it is in
up status physically, the physical status of MFR is up. Only when all the physical
interfaces bundled on it are physically down can the physical status of MFR turns
to down. The link protocol status of MFR interface depends on LMI packet
negotiation.

For description convenience, the interface that uses frame relay or MFR as link
layer protocol will be called as frame relay interface uniformly, and MFR bundle
interface will be called as MFR interface instead.

Configuring MFR Bundle
Identifier
Perform the following configuration in MFR interface view.
By default, bundle identifier is “mfr + frame relay bundle number” such as
mfr4/0/123. This identifier is only locally valid.
mfr4/0/123. This identifier is only locally valid.

Fragmentation
MFR interfaces support the fragmentation of packets when sending and receiving
