Configuring a frame relay local virtual circuit
On a DCE or NNI frame relay main interface or subinterface, you must manually create virtual circuits.
On a DTE main interface, you do not necessarily create virtual circuits manually because the device 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 virtual circuits on a DTE interface, make sure their DLCIs are identical to those used on the DCE.
A virtual circuit number is unique on a physical interface.
If the DLCI of a PVC is changed on the DCE interface, you can perform one of the following operations to enable the DTE to relearn the correct address mappings as soon as possible:
Restart both the DCE and DTE interfaces.
Execute the reset fr inarp command in an IPv4 network or the reset fr ind command in an IPv6 network on both ends.
Before doing that, make sure no services will be interrupted.
To configure a frame relay local virtual circuit:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Configure a virtual circuit on the interface. | fr dlci dlci-number | By default, no virtual circuits are created on interfaces. |
