316 C 4: L L P
HAPTER INK AYER ROTOCOL
Description
Using the interface mfr command, you can create a multilink frame relay bundle
interface or sub-interface and enter the corresponding interface view. Using the
undo interface mfr command, you can delete a specified multilink frame relay
bundle interface or sub-interface.
By default, there is no multilink frame relay interface or sub-interface.
Before using the undo interface mfr command to delete an MFR interface, you
must delete all physical interfaces from the MFR interface.
Before an MFR sub-interface is created, the MFR interface must be created first.
For the related commands, see link-protocol fr mfr and mfr bundle-name.
Example
Create a multilink frame relay bundle interface with a point-to-multipoint
sub-interface.

Parameter
nonstandard: Nonstandard compatible encapsulation format.
ietf: Default encapsulation format according to the Internet Engineering Task Force
(IETF) standard.
Description
Using the link-protocol fr command, you can encapsulate interface link layer
protocol as Frame Relay.
By default, the link-layer protocol encapsulated on the interface is PPP, and the
frame relay encapsulation format is IETF.
In VRP, the Frame Relay encapsulation can be either ietf or nonstandard
compatible encapsulation (nonstandard). IETF encapsulation conforms to
RFC1490, that is, it supports the IETF standard.
