interface-number: MFR interface number, in the range 0 to 1023.

interface-number.subnumber: MFR subinterface number, of which, 
interface-number is the main interface number, and subnumber is subinterface 
number. The subnumber argument ranges from 0 to 1023.

Use the interface mfr command to create a multilink frame relay bundle 
interface or subinterface and enter the corresponding interface view.

Use the undo interface mfr command to delete a specified multilink frame relay 
bundle interface or subinterface.

By default, there is no multilink frame relay interface or subinterface.

Before an MFR subinterface is created, the MFR interface must be created first.

Before using the undo interface mfr command to delete an MFR interface, you 
must delete all physical interfaces from the MFR interface.

For MFR interface, if there is one bundle link is in up state, the MFR physical state 
is up. Moreover, all bundle links should be tagged as down before the bundle is 
down. The link layer protocol on MFR interface is determined by LMI packet 
negotiation.

# Create a multilink frame relay bundle interface MFR4 with a point-to-multipoint 
subinterface.
