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
