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 193.44.69.1/30 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 193.44.69.1 255.255.255.252
Step 3: (VALID ONLY FOR T1 INTERFACES)
Specify the group of DS0s used for signaling on the T1 interface by creating a
tdm-group . Group any number
of aggregate DS0s together to create a data pipe for layer 2 signaling. Also use the
tdm-group command to
specify the per-DS0 signaling rate on the interface. For example, the following creates a tdm-group labeled
9
containing 20 DS0s (each DS0 having a data rate of 56 kbps).
(config)#
interface t1 1/1
(config-t1 1/1)# tdm-group 9 timeslots 1-20 speed 56
(config-t1 1/1)# exit
Step 4:
Make the association between the layer 2 endpoint and the physical interface using the
cross-connect
command. Supported layer 2 protocols include frame relay and point-to-point protocol (PPP). For example, the
following creates a cross-connect (labeled
5 ) to make an association between the frame relay virtual interface
(
fr 7 ) and the tdm-group configured on interface t1 1/1 ( tdm-group 9 ).
(config)#
cross-connect 5 t1 1/1 9 fr 7
Usage Examples
The following example creates a frame relay virtual interface (labeled 1 ) and enters the Frame Relay Interface
Configuration Mode:
(config)#
interface fr 1
(config-fr 1)#
