387Use the undo fr dlci command to cancel the configuration.When the frame relay interface type is DCE or NNI, it is necessary to manuallyconfigure virtual circuit for interface (either main interface or subinterface). Whenthe frame relay interface type is DTE, if the interface is main interface, the systemwill automatically configure the virtual circuit according to the peer device.The virtual circuit number on the physical interface is unique.Example # Assign a virtual circuit with DLCI 100 to frame relay interface Serial 2/0. system-view[Sysname] interface serial 2/0[Sysname-Serial2/0] fr dlci 100[Sysname-fr-dlci-Serial2/0-100]fr dlci-switchSyntax fr dlci-switch in-dlci interface interface-type interface-number dlci out-dlciundo fr dlci-switch in-dlciView Frame relay interface view, MFR interface viewParameter in-dlci: DLCI in the packets received on the interface, in the range 16 to 1007.interface interface-type interface-number: Specifies an interface by its type andnumber.dlci out-dlci: DLCI in the sent packets. It is in the range 16 to 1007.Description Use the fr dlci-switch command to configure a static route for frame relay PVCswitching.Use the undo fr dlci-switch command to delete a static route for frame relayPVC switching.By default, no static route is configured for frame relay PVC switching.Before the static route of frame relay PVC is configured, it is necessary to enablethe frame relay PVC switching first by using the fr switching command.The default type of the forwarding interface can be frame relay or MFR. You canhowever specify a tunnel interface for forwarding, if one has been configured,thus transmitting frame relay packets over IP networks.Related command: fr switching.Example # Configure a static route, allowing the packets on the link with DLCI of 100 onSerial 2/0 to be forwarded over the link with DLCI of 200 on interface Serial 2/1.
