Configuring Frame Relay virtual circuits

You can configure one network/virtual circuit for each Frame Relay DLCI.

Using CLI to configure

Follow these steps to configure a frame relay virtual circuit:

1.Define a virtual circuit.

Frame-relay subinterface <integer>

<integer> is the virtual circuit number, from 1 to 10.

After you configure a virtual circuit number, the CLI returns a prompt that specifies your current working location. For example, the following command defines virtual circuit 1 on the frame relay circuit.

CES(config-if)#frame-relay subinterface 1 CES(config-subif)#

2.Add a description for this virtual circuit.

CES(config-subif)#description <virtual-circuit name>

<virtual circuit name> can be any wording used to properly describe this virtual circuit.

Example:

CES(config-subif)# description “virtual circuit1”

3.Define the Frame Relay encapsulation.

CES(config-subif)# encapsulation <encaps_type>

<encaps_type> is the Frame Relay encapsulation type. Currently, the only encaps type is MPoFR.

Example:

CES(config-subif)#encapsulation MpoFR

4.Define whether the virtual circuit is a public or private interface.

CES(config-subif)#(no) public

By default, the virtual circuit is set to public.

Example on how to change virtual circuit to be a private interface:

CES(config-subif)#no public

Example on how to change virtual circuit to be a public interface.

CES(config-subif)#public
