2Configuration Related to Frame Relay Switching

Only some simple Frame Relay switching configurations are covered in this section. For other configurations, refer to the Link Layer Protocol.

Configure the commands fr switch and fr switching in system view, and perform other configurations in synchronous serial interface view.

In addition to Frame Relay switching connections between serial interfaces, the fr switch command also supports the Frame Relay switching connections between ISDN BRI, ISDN PRI and dialer interfaces.

3BDR-related Configuration

■Adopt legacy BDR

If legacy BDR is adopted to implement Frame Relay over ISDN, the user can refer to Dial-upof this manual for all the configurations except for the link layer protocol on the dialer or physical ISDN interface. The link layer protocol should be configured through the link-protocol fr command.

Perform the following configuration in physical ISDN or dialer interface view.

Table 315 Configure the link layer protocol of the interface

Operation	Command
Configure the link layer protocol of the	link-protocol fr [ ietf
interface to Frame Relay	nonstandard ]

The two ends of a BDR call should work with the same link layer protocol.

For a physical interface (such as an ISDN BRI or PRI interface), both the D channel and B channel are configured with Frame Relay.
