3. Create a static Frame Relay
address-to-DLCI map.
fr map ip { ip-address | default }
dlci-number
By default, no static Frame Relay
address-to-DLCI maps are
configured.
When the DLCI specified in this
command does not exist, the DLCI
is automatically created.

Configuring Frame Relay subinterfaces
Frame Relay provides main interfaces and subinterfaces. A subinterface is a logical interface. It can be
configured with protocol addresses and virtual circuits. One physical interface can include multiple
subinterfaces. The subinterfaces and main interfaces can all be configured with virtual circuits to connect
to peer devices.
Frame Relay subinterfaces include the following types:
• Point-to-point (P2P) subinterface—A P2P subinterface connects to a single peer device.
• Point-to-multipoint (P2MP) subinterface—A P2MP subinterface connects to multiple peer devices.
A P2MP subinterface can be configured with multiple virtual circuits. An address-to-DLCI map can
be configured for each virtual circuit and its connected peer network address. Address-to-DLCI
maps can be dynamically configured through InARP or manually configured.
The methods of configuring a virtual circuit and address-to-DLCI map for P2P subinterfaces and P2MP
subinterfaces have the following differences:
• P2P subinterface—Because a P2P subinterface has only one peer address, the peer address is
determined when a virtual circuit is configured for the subinterface. You cannot configure static
address-to-DLCI maps or enable InARP for a P2P subinterface.
• P2MP subinterface—For a P2MP subinterface, a peer address can be mapped to the local DLCI
through static address-to-DLCI maps or InARP. To enable InARP for dynamic address mapping on a
P2MP subinterface, you only need to enable InARP on the main interface. If static address-to-DLCI
maps are needed, you must configure a static address-to-DLCI map for each virtual circuit.
