Configuring A Frame Relay Local Virtual Circuit; Configuring A Frame Relay Subinterface - H3C SR6600 Configuration Manual

To do...
Enter interface view
Enable frame relay InARP for
dynamic address mapping
You do not need to configure DLCIs for PVCs if static address mappings are configured.
Do not configure any static address mapping on a P2P subinterface, because a P2P subinterface
carries only one PVC.

Configuring a Frame Relay Local Virtual Circuit

On a DCE or NNI frame relay main interface or subinterface, you need to manually create virtual
circuits.
On a DTE main interface, you do not necessarily create virtual circuits manually because the router can
automatically create virtual circuits according to the settings received from the DCE side. On a DTE
subinterface, the virtual circuit must be manually created. When manually creating a virtual circuit on a
DTE interface, ensure that its DLCI is identical to the one used on the DCE.
A virtual circuit number is unique only on a physical interface.
Follow these steps to configure a frame relay local virtual circuit
To do...
Enter system view
Enter interface view
Configure a virtual circuit on the
interface
If the DLCI of a PVC is changed on the DCE interface, you can reset both the DCE and DTE interfaces
or execute the reset inarp command on both ends to enable the DTE to re-learn the correct address
mappings as soon as possible. Before doing that, ensure that this does not interrupt any services.

Configuring a Frame Relay Subinterface

Frame relay offers two types of interfaces: main interface and subinterface. The subinterface is of
logical structure, which can be configured with protocol address and virtual circuit. One physical
