Configure Static Address Mapping on Multipoint Subinterfaces

A static map links a specified next hop protocol address to a specified
DLCI. Static mapping removes the need for Inverse ARP requests;
when you supply a static map, Inverse ARP is automatically disabled
for the specified protocol on the specified DLCI.

You must use static mapping if the router at the other end either does
not support Inverse ARP at all or does not support Inverse ARP for a
specific protocol that you want to use over Frame Relay.

To establish static mapping according to your network needs, perform
one of these tasks in interface configuration mode:

z

Define the mapping between a next hop protocol address and the
DLCI used to connect to the address.

frame-relay map

protocol protocol-address

dlci

[broadcast] [ietf] [cisco]

z

Define a DLCI used to send ISO CLNS frames.

frame-relay map clns

dlci

[broadcast]

z

Define a DLCI used to connect to a bridge.

frame-relay map bridge

dlci

[ietf]

broadcast

Use these keywords to specify the protocols:

z

ip

—IP

z

ipx

—Novell IPX

z

clns

—ISO CLNS
