282 CHAPTER 17: CONFIGURING FRAME RELAY
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, the IP addresses 110.0.0.2 and 120.0.0.2, and the DLCI numbers 100
and 200.

III. Configuration Procedure
1 Configure RouterA
a Configure the BDR parameters on the interface 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
b Configure the Frame Relay 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.
2 Configure RouterB
a Configure BDR and Frame Relay parameters on the PRI interface.
