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.

Configuring a frame relay subinterface
Frame relay offers main interface and subinterface. The subinterface is of logical structure, which
can be configured with protocol address and virtual circuit. One physical interface can include
multiple subinterfaces, which do not exist physically. However, for the network layer, the subinterface
and main interface make no difference and both can be configured with virtual circuits to connect to
remote devices.
The subinterfaces of frame relay include the following types:
• Point-to-point (P2P) subinterface.
• Point-to-multipoint (P2MP) subinterface.
