IDSL Configuration with Frame Relay

IDSL Configuration with Frame Relay

The following procedure is an example of how to configure IDSL with Frame Relay.

Step 1 In global configuration mode, specify a name for the router. For example: router(config)# hostname 802

Step 2 Specify a username and password. The username is the destination router’s hostname. The password must be the same for both the host and destination routers. For example:

router(config)# username isp password cisco Step 3 Set the switch type. For example:

router(config)# isdn switch-type basic-5ess

Step 4 Set the BRI interfaces to use the ISDN physical connection as a leased-line service. The following example sets the line speed at 144 kbps:

router(config)# isdn leased-line bri0 144 router(config)# isdn leased-line bri0.1 144

Step 5 Change to interface command mode. For example: router(config)# interface ethernet0

Step 6 Enter an IP address. For example:

router(config-if)#ip address 192.168.2.1 255.255.255.0

Step 7 Enable Network Address Translation (NAT) on your LAN. The inside network address is not directly routed to the Internet but is subject to translation to a routable address outside the LAN.

router(config-if)# ip nat inside Step 8 Change to BRI interface.

router(config-if)# interface bri0 Step 9 Configure interface with no IP address.

router(config-if)# no ip address

Step 10 Configure NAT so that the inside network address will be translated to a valid Internet address. router(config-if)# ip nat outside

Step 11 Specify the encapsulation type. In the following example, IETF is used to connect to non-Cisco routers. router(config-if)#encapsulation frame-relay ietf

Step 12 Specify the Local Management Interface (LMI) type used by the Frame Relay switch. For example: router(config-if)#frame-relay lmi-type ansi

Step 13 Specify the subinterface point-to-point. For example: router(config-if)#interface bri0:1 point-to-point

Step 14 Specify the IP address on the subinterface. For example: router(config-if)#ip address 209.188.2.2 255.255.255.0
