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 method:
(config)#
interface frame-relay 1
(config-fr 1)#
frame-relay lmi-type cisco
2. Create the sub-interface and configure the PVC parameters (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
command set 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
7
and sets the signaling method to
ansi
.
(config)#
interface frame-relay 7
(config-fr 7)#
frame-relay lmi-type ansi
Step 2:
Create the sub-interface and configure the PVC parameters. Using the sub-interface command set, apply
access policies to the interface, create bridging interfaces, configure dial-backup, assign an IP address, and
set the PVC data-link control identifier (DLCI). For example, the following creates a frame relay sub-interface
labeled
22,
sets the DLCI to
30,
and assigns an IP address of
193.44.69.253
to the interface.
(config-fr 7)#
interface fr 7.22
(config-fr 7.22)#
frame-relay interface-dlci 30
(config-fr 7.22)#
ip address 193.44.69.253 255.255.255.252
