WAN Interface Frame Relay Configuration

Physical Communications Settings

You may need to set the baud rate, sync/async operation, and other physical communications parameters for the WAN interface. These parameters will depend on the line communications device you are using.

RV: Use the WAN - General window.

CL: Use interface(misc) and then wan serial(set).

WAN Interface Frame Relay Configuration

This section covers the settings required for Frame Relay operation of the BR Router WAN interfaces. In general, the parameters listed here should be set for each WAN interface on which you plan to use Frame Relay. Note that some WAN interfaces can be running Frame Relay while others are running PPP.

There are a few differences between the capabilities of the V.35 WAN interface and the RS-232 WAN interface. The V.35 interface can only be run synchronously, at rates up to 2 Mbps per second. The RS-232 interface can be run synchronously or asynchronously, at rates up to 256Kbps (sync), or 230.4Kbps (async).

IP Protocol

Required for IP

Frame Relay operation requires that the WAN interface is set to be a “numbered interface.” This means that the interface (and thus the Frame Relay network) must have an IP address, etc.

•IP numbered interface

•IP Address

•IP Subnet mask

•IP Broadcast Address

RV: Use the WAN - IP screen to set these parameters.

CL: Use the interface(misc) and ip wan(set) commands.

Suggested for IP

These parameters help supply information about the segment that the interface is connected to. With this information, routing can take place.

•IP RIP 1 (Routing Information Protocol version 1) and/or
