Whether the mapping of a DLCI to a remote IP address happens dynamically or statically, the DLCI that is used does not have to be the same number at both ends of the PVC.

If you use static address mapping, you must use the frame-relay map command to statistically map destination network protocol addresses to a designated DLCI. In this figure, the central site router is configured with static maps to both branch routers, Branch A and Branch B.

The static address mapping command syntax is as follows:

frame-relay map protocol protocol-address dlci [broadcast] [ietf | cisco]

The following table describes the frame-relay map command syntax. frame-relay map Command




Selects the protocol type. Commonly used protocols are dlsw, ip, and ipx.


Specifies the destination protocol address.


Specifies the DLCI number used to connect to the specified protocol address on the interface.


(Optional) Specifies that broadcasts should be forwarded when multicast is not enabled.


(Optional) Enables the Internet Engineering Task Force (IETF) encapsulation.


(Optional) Enables the Cisco encapsulation.
