Configuration restrictions and guidelines

When you configure local Frame Relay virtual circuits, follow these restrictions and guidelines:
•
When manually creating virtual circuits on a DTE interface, make sure their DLCIs are the same
as those used on the DCE.
•
If the DLCI of a virtual circuit changes on a DCE interface, perform one of the following tasks for
the DTE to quickly relearn the correct address-to-DLCI maps. Before performing either of the
following tasks, make sure no services will be interrupted.
Reset both the DCE and DTE interfaces.

Execute the reset inarp command on both ends.

•
The DLCI of a virtual circuit must be unique on a main interface and all its subinterfaces.

Configuration procedure

To configure a local Frame Relay virtual circuit:
Step
1. Enter system view.
2. Enter interface view.
3. Create a virtual circuit on the
interface.
4. (Optional.)
encapsulation type for the
virtual circuit.
5. (Optional.) Allow broadcast
packets on the virtual circuit.

Configuring Frame Relay address mapping

Use either of the following methods to configure Frame Relay address mapping:
•
Static—Manually create static address-to-DLCI maps between peer IPv4 or IPv6 addresses
and local DLCIs. Use this method when the network topology is stable and no new users are
expected for a specific period of time. Because static address-to-DLCI maps do not change, the
network connections are stable, and attacks from unknown users are avoided.
•
Dynamic—Use InARP or IND to dynamically create IPv4 or IPv6 address-to-DLCI maps. Use
this method in complex networks. Make sure the peer devices also support InARP or IND.

Remarks
N/A
The interface can be a main
interface or subinterface.
By default, no virtual circuits exist.
By default, a virtual circuit uses
the encapsulation type configured
on its interface.
By default, broadcast packets are
forbidden on static virtual circuits
and allowed on dynamic virtual
circuits.
When a virtual circuit allows
broadcast packets, the broadcast
or multicast packets on the Frame
Relay interface of the virtual
circuit are also transmitted on the
virtual circuit.
