Basic Frame-Relay Configuration

with both Inverse-ARP and

Frame-Relay Map Command



Here, we will talk about two options for configuring Frame-Relay Maps. One is Inverse-ARP and the other is with “frame-relay map” command. To show this in a basic topology, we will use the below topology configured with three Cisco 3600 series routers.


Firstly, we will start to do the configuration for Inverse-ARP way.The configurations are below:

Istanbul Router Configuration

Istanbul (config) # interface serial 0/0
Istanbul (config-if) # ip address 210.0.0.1 255.255.255.0
Istanbul (config-if) # encapsulation frame-relay
Istanbul (config-if) # frame-relay interface-dlci 100
Istanbul (config-if) # no shutdown
Istanbul (config-if) # end
Istanbul # write

Note 1 : In Cisco routers you must enter “frame-relay switching” command to configure the router as a frame-relay switch.

Note 2 : If there is another router aside from Cisco router, then you must use “encapsulation frame-relay ietf” command.

Frame-Relay Switch Configuration

FR_Switch (config) # interface serial 0/0
FR_Switch (config-if) # no ip address
FR_Switch (config-if) # encapsulation frame-relay
FR_Switch (config-if) # clock rate 64000
FR_Switch (config-if) # frame-relay intf-type dce
FR_Switch (config-if) # frame-relay route 100 interface serial 0/1 300
FR_Switch (config-if) # no shutdown
FR_Switch (config-if) # exit
FR_Switch (config) # interface serial 0/1
FR_Switch (config-if) # no ip address
FR_Switch (config-if) # encapsulation frame-relay
FR_Switch (config-if) # clock rate 64000
FR_Switch (config-if) # frame-relay intf-type dce
FR_Switch (config-if) # frame-relay route 300 interface serial 0/0 100
FR_Switch (config-if) # no shutdown
FR_Switch (config-if) # end
FR_Switch # write

Ankara Router Configuration

Ankara (config) # interface serial 0/0
Ankara (config-if) # ip address 210.0.0.2 255.255.255.0
Ankara (config-if) # encapsulation frame-relay
Ankara (config-if) # frame-relay interface-dlci 300
Ankara (config-if) # no shutdown
Ankara (config-if) # end
Ankara # write

To check the connection between the routers, you can use the below ping commands:

Istanbul # ping 210.0.0.2
Ankara # ping 210.0.0.1

Now, it is time to do this Frame-Relay Map with “Frame-Relay Map” command instead of Inverse-ARP. This is the static way of mapping.

Make the below configuration on Istanbul and Ankara routers. FR_Switch before configuration will remain.

Istanbul Router Configuration

Istanbul (config) # interface serial 0/0
Istanbul (config-if) # ip address 210.0.0.1 255.255.255.0
Istanbul (config-if) # encapsulation frame-relay
Istanbul (config-if) # no frame-relay inverse-arp
Istanbul (config-if) # frame-relay map ip 210.0.0.2 100
Istanbul (config-if) # no shutdown
Istanbul (config-if) # end
Istanbul # write

Ankara Router Configuration

Ankara (config) # interface serial 0/0
Ankara (config-if) # ip address 210.0.0.2 255.255.255.0
Ankara (config-if) # encapsulation frame-relay
Ankara (config-if) # no frame-relay inverse-arp
Ankara (config-if) # frame-relay map ip 210.0.0.1 300
Ankara (config-if) # no shutdown
Ankara (config-if) # end
Ankara # write

Here again to check the connection between routers use the below ping commands:

Istanbul # ping 210.0.0.2
Ankara # ping 210.0.0.1

We can also use the below control commands:

“show frame-relay map”

“show frame-relay pvc”

“show frame-relay route”


“Show frame-relay map” command’s one of the output will be dynamic, if you use it with Inverse-ARP or it will be static, if you use it with ”frame-relay map command” . Here our last configuration is static, so it is shown as static. Additionally it gives the map status if it is active or passive.





“show frame-relay pvc” gives information about the pvc status.Some expressions mention the status of the pvc, these are:

Active = There is no problem.
Deleted = There is no definion on Frame Relay Switch and no lmi packet traffic.
Inactive = There is lmi traffic but there is a problem o end-to-end connection.
<>



“show frame-relay route” shows the route definitions on Frame Relay Switch.
