Configure Frame Relay over Other Protocols 273
2 Configuration 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.
Table 314 Configure the commands related to Frame Relay switching
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.
3 BDR-related Configuration
■ Adopt legacy BDR
If legacy BDR is adopted to implement Frame Relay over ISDN, the user can
refer to Dial-up of 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
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.
