Define Subinterface Addressing
For point-to-point subinterfaces, the destination is presumed to be
known and is identified or implied in the
known and is identified or implied in the
frame-relay inter-
face-dlci
command. For multipoint subinterfaces, the destinations
can be dynamically resolved through the use of Frame Relay Inverse
ARP or can be statically mapped through the use of the
ARP or can be statically mapped through the use of the
frame-
relay map
command.
Addressing on Point-to-Point Subinterfaces
If you specified a point-to-point subinterface in Step 3 unde
, type (in interface configuration mode):
frame-relay interface-dlci
dlci [option]
If you define a subinterface for point-to-point communication, you
cannot reassign the same subinterface number to be used for multi-
point communication without first rebooting the router or access
server. Instead, you can simply avoid using that subinterface numbe
and use a different subinterface number instead.

Examples: Basic Subinterface
In this example, subinterface 1 models a point-to-point subnet and sub-
interface 2 models a broadcast subnet. For emphasis, the multipoint
keyword is used for serial subinterface 2, even though a subinterface
is multipoint by default.
