Step 2:
Create the sub-interface and configure the PVC parameters. Using the sub-interface, 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
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
contiguous 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
