252 CHAPTER 17: CONFIGURING FRAME RELAY
b Configure virtual circuit of Frame Relay sub-interface
In interface view, perform the following task to configure the virtual circuit of
Frame Relay sub-interface.
Table 283 Configure virtual circuit of Frame Relay sub-interface
c Configure Sub-Interface PVC and Establish Address Mapping
Since there is only one peer address for point-to-point sub-interface, the peer
address is determined when a PVC is configured for the sub-interface. For
point-to-multipoint sub-interface, the peer address and local DLCI can be
determined by configuring static address mapping or using inverse address
resolution protocol.
Establishing static address mapping of Frame Relay sub-interface
Table 284 Establish static address mapping
Applying dynamic address mapping to the sub-interface
Table 285 Configure Frame Relay dynamic address mapping
By default, all the sub-interfaces are enabled to use dynamic inverse-arp.
8 Configure Frame Relay PVC Switching
Router routers can be used as Frame Relay switches to provide the function of
Frame Relay PVC switching. There are two ways to configure the Frame Relay
switching:
configuring the Frame Relay switched route or configuring the Frame
Relay switched PVC.
a Enable the Frame Relay switching
