Usage Examples

The following example creates a Frame Relay endpoint and connects it to the T1 1/1 physical interface:

1. Create the Frame Relay virtual endpoint and set the signaling metho d:

(config)#

interface frame-relay 1

(config-fr 1)#

frame-relay lmi-type cisco

2. Create the sub-interface and configure the PVC p arameters (including DLCI and IP address):

(config-fr 1)#

interface fr 1.1

(config-fr 1.1)#

frame-relay interface-dlci 17

(config-fr 1.1)#

ip address 168.125.33.252 255.255.255.252

3. Create the TDM group of 12 DS0s (64K) on the T1 physical interface:

(THIS STEP IS ONLY VALID FOR T1 INTERFACES.)

(config)#

interface t1 1/1

(config-t1 1/1)#

tdm-group 1 timeslots 1-12 speed 64

(config-t1 1/1)#

exit

4. Connect the Frame Relay sub-interface with port T1 1/1:

(config)#

cross-connect 1 t1 1/1 1 fr 1

Technology Review

Creating an endpoint that uses a layer 2 protocol (such as Frame Relay) is generally a four-step process:

Step 1:

Create the Frame Relay virtual endpoint (using the

interface frame-relay

command) and set the signaling

method (using the

frame-relay lmi-type

command). Also included in the Frame Relay virtual endpoint are all

the applicable Frame Relay timers logging thresholds, encapsulation types, etc. Generally, most Frame Relay

virtual interface parameters should be left at their default state. For example, the following creates a Frame

Relay interface labeled

and sets the signaling method to

ansi

(config)#

interface frame-relay 7

(config-fr 7)#

frame-relay lmi-type ansi
