Frame Relay Switching Connection through Frame Relay over ISDN

Typical Frame Relay Configuration Example 283

[Router-Serial2:15]dialer bundle-member 20

For configuring the BDR and Frame Relay parameters on Dialer1, refer to the configuration on Dialer0. The user only needs to change the IP address to 120.0.0.2, DLCI number to 200, and configure to receive the incoming calls from the number 660208 and assign Dialer1 to Dialer Bundle 20.

I. Networking Requirements

RouterB (DCE) is connected to the ISDN interface on RouterA (DTE) via ISDN at one side and RouterC (DTE) via the serial interface at another side. With the Frame Relay switching function of DCE, routers can interwork across ISDN. RouterA adopts legacy BDR to make calls while RouterB adopts dialer profiles. To establish a PVC, the call must be originated from RouterA.

On RouterA, two BRI interfaces, Bri0 and Bri1, are available. Bri0 is assigned with the ISDN number 660218, the IP address 110.0.0.1 and the DLCI number 100. Bri1 is assigned with the ISDN number 660208, the IP address 120.0.0.1 and the DLCI number 200. On RouterB, one PRI interface is available for providing services for two dialer interfaces. This PRI interface is assigned with the ISDN number 660045, and the DLCI numbers 100 and 200 respectively for these two dialer interfaces. At the same time, RouterB is connected to RouterC via a serial interface, which is assigned with the DLCI numbers 300 and 400. The serial interface on RouterC is available with 2 sub-interfaces, which are respectively assigned with the IP addresses 110.0.0.2 and 120.0.0.2, and DLCI numbers 300 and 400.

III. Configuration Procedure

1Configure RouterA

a Configure the BDR-related parameters on Bri0.

[Router]dialer-rule 1 ip permit

[Router]interface bri 0 [Router-Bri0]link-protocol fr

[Router-Bri0]ip address 110.0.0.1 255.255.255.0

[Router-Bri0]dialer enable-legacy

[Router-Bri0]dialer-group 1

[Router-Bri0]dialer number 660045

bConfigure the Frame Relay-related parameters on Bri0.

[Router-Bri0]fr map ip 110.0.0.2 dlci 100

[Router-Bri0]fr dlci 100

For configuring the BDR and Frame Relay parameters on Bri1, refer to the configuration on Bri0. The user only needs to change the IP address to 120.0.0.1, DLCI number to 200, and address mapping to static address mapping.
