89By default, no multilink frame relay interface or subinterface exists. On creation, the type of an MFRsubinterface is p2mp by default.To create an MFR subinterface successfully, make sure the MFR interface already exists.To use the undo interface mfr command to delete an MFR interface, delete all physical interfaces from theMFR interface.For MFR interface, if one bundle link in up state exists, the MFR physical state is up. Moreover, all bundlelinks should be tagged as down before the bundle is down. The link layer protocol on MFR interface isdetermined by LMI packet negotiation.Examples# Create a multilink frame relay bundle interface MFR 6/1/12 with a point-to-multipoint subinterface. system-view[Sysname] interface MFR 6/1/12[Sysname-MFR6/1/12] quit[Sysname] interface MFR 6/1/12.1[Sysname-MFR6/1/12.1]link-protocol fr mfrSyntaxlink-protocol fr mfr interface-numberViewInterface viewDefault level2: System levelParametersinterface-number: MFR interface number.DescriptionUse the link-protocol fr mfr command to configure the current physical interface as an MFR bundle linkand bind it to an MFR interface.By default, an interface is not bound to any MFR interface.When this command is configured, the specified MFR interface must exist. A maximum of 16 physicalinterfaces can be bundled onto an MFR interface, but only 12 of them stay up at the same time.To delete a physical interface from an MFR interface, use the link-protocol command to apply a link layerprotocol of non-frame relay MFR to the interface.After a physical interface is encapsulated as MFR format, the interface belongs to MFR and is notallowed to be configured using the commands related to FR except MFR.Examples# Configure Serial 6/1/8:10 as a bundle link and add it onto the Frame Relay bundle interfaceMFR6/1/12. system-view[Sysname] interface Serial 6/1/8:10[Sysname-Serial6/1/8:10] link-protocol fr MFR 6/1/12
