The
dlci parameter indicates the DLCI on the local interface with which you want to
exchange Inverse ARP messages. Inverse ARP is on by default and does not
appear in the con?¬?guration output.
Consider the following con?¬?guration, where IP is the protocol, and the DLCI is 16:
RouterX(config-if)# frame-relay inverse-arp ip 16
When the remote router does not support Inverse ARP, the Frame Relay peers have different
Frame Relay encapsulation types. Or when you want to control broadcast and multicast
traf?¬?c over the PVC, you must statically map the local DLCI to the remote router network
layer address. These static Frame Relay map entries are referred to as static maps.
336 Chapter 8: Extending the Network into the WAN
Use the following command to statically map the remote network layer address to the local
DLCI:
RouterX(config-if)# ffrraammee--rreellaayy mmaapp protocol protocol-address dlci [bbrrooaaddccaasstt]
[iieettff | cciissccoo | ppaayyllooaadd--ccoommpprreessss ppaacckkeett--bbyy--ppaacckkeett]
Table 8-2 details the parameters for this command.
You can con?¬?gure subinterfaces in one of the following two modes:
?– Point-to-point: A single point-to-point subinterface is used to establish one PVC
connection to another physical interface or subinterface on a remote router.
