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
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 , apply access policies to
the interface, create bridging interfaces, configure 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
bind
command.
Supported layer 2 protocols include Frame Relay and point-to-point protocol (PPP). For example, the following
creates a bind (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)#
bind 5 t1 1/1 9 fr 7
