Configuring the Frame-Relay Virtual Interface
The following steps outline configuring a frame-relay virtual interface (labeled 1) using
a single DLCI back to the corporate router (defined as DLCI 16).
1. At the (config)# prompt, enter interface fr 1 to create a frame-relay virtual interface
labeled 1.
2. If the default setting of ansi was changed, enter frame-relay lmi-type ansi to
configure frame-relay virtual interface 1 to use ANSI (Annex D) signaling.
3. Enter no shutdown to activate the virtual interface to pass data.
4. Enter exit to return to the global configuration mode.
5. The unit has a factory default PPP 1 interface. Enter the command no ppp 1 to
remove this interface.

Creating the PVC and Assigning an IP Address
1. At the (config)# prompt, enter interface fr 1.16 to create a PVC assigned to frame-
relay virtual interface 1. This activates the configuration parameters for the PVC.
Your prompt should now display (config-fr 1.16)#.
2. Enter frame-relay interface-dlci 16 to assign DLCI 16 to this PVC.
3. Enter ip address 192.168.72.1 255.255.255.252 to assign an IP address of
192.168.72.1 for this PVC using a 30-bit subnet mask.
4. Enter exit to return to the global configuration mode.
5. If you are configuring the NetVanta for use in a frame-relay application and have
completed this step, skip to step 8.
The default encapsulation is RFC 1490 or IETF. Make certain the remote unit uses the same
encapsulation for frame-relay.

Configuring the Virtual PPP Interface
The following steps show how to configure a PPP virtual interface (labeled 1) to the
corporate router. Skip to step 8 if you are using frame-relay.
1. At the (config)# prompt, enter interface ppp 1 to create a PPP virtual interface
labeled 1.
2. Enter ip address 192.168.72.1 255.255.255.252 to assign an IP address to the
PPP endpoint using a 30-bit mask.
3. Enter no shutdown to activate the virtual interface to pass data.
4. Enter exit to return to the global configuration mode.
