How to configure frame realy

2. Change the encapsulation
 Go in interface mode and select the Frame Relay
encapsulation on the interface. There are two types of
Frame Relay encapsulations: Cisco and IETF. Cisco is the
default. Syntax to set your encapsulation is
encapsulation frame-relay [ietf]
Configure LMI type
 The three LMI types are Cisco, Ansi, and Q933a. For IOS
11.2 and higher, the LMI type is automatically detected
frame-relay lmi-type [cisco | ansi | 933a]

3. Configure Frame Relay map
 configuring a static Frame Relay map, is optional unless you are
using subinterfaces. The Frame Relay map will map a Layer 3
address to a local DLCI. This step is optional because inverse-arp
will automatically perform this map for you. The syntax for a
Frame Relay map is as follows:
frame-relay map protocol address dlci [broadcast] [cisco |
ietf]

4. Configure subinterfaces
 If you are using a routing protocol in a hub-and-spoke topology,
you will probably want to use subinterfaces to avoid the split-
horizon problem. To configure a subinterface, remove the IP
address off the main interface and put it under the subinterface.
Configuring a subinterface involves assigning it a number and
specifying the type. The following command creates point-to-
point subinterface serial0/0.1
Router(config)#interface serial0/0.1 point-to-point
 To create a multipoint subinterface, enter multipoint instead:
Router(config)#interface serial0/0.1 multipoint

5. Assign IP address to subinterface
 After entering one of these commands you will be taken to the
subinterface configuration mode where you can enter your IP
address:
Router(config-subif)#ip address 10.0.0.2 255.0.0.0
 If you are using a multipoint subinterface, you will need to
configure frame-relay maps and you cannot rely on inverse-arp.
 If you are using a point-to-point subinterface, you will need to
assign a DLCI to the subinterface. This is only for point-to-point
subinterfaces; this is not needed on the main interface or on
multipoint subinterfaces. To assign a DLCI to a point-to-point
subinterface, enter the following command under the
subinterface:
frame-relay interface-dlci dlci

7.  Now first configure R1. Fast Ethernet port and hostname is
already configured. Double click on R1 and configure serial port
for frame relay encapsulation and further create sub interface
for connecting R2, R3, R4. Configure also static route for
connecting remaining network.
Configure R1
R1>enable
R1#configure terminal
R1(config)#interface serial 0/0/0
R1(config-if)#encapsulation frame-relay
R1(config-if)#no shutdown
R1(config-if)#exit

8.  R1(config-subif)#interface serial 0/0/0.102 point-to-point
 R1(config-subif)#ip address 192.168.1.245 255.255.255.252
 R1(config-subif)#frame-relay interface-dlci 102
 R1(config-subif)#exit
 R1(config)#interface serial 0/0/0.103 point-to-point
 R1(config-subif)#ip address 192.168.1.249 255.255.255.252
 R1(config-subif)#frame-relay interface-dlci 103
 R1(config-subif)#exit
 R1(config)#interface serial 0/0/0.104 point-to-point
 R1(config-subif)#ip address 192.168.1.253 255.255.255.252
 R1(config-subif)#frame-relay interface-dlci 104
 R1(config-subif)#exit
 R1(config)#ip route 192.168.1.64 255.255.255.224 192.168.1.246
 R1(config)#ip route 192.168.1.96 255.255.255.224 192.168.1.250
 R1(config)#ip route 192.168.1.128 255.255.255.224 192.168.1.254
 R1(config)#exit

9. configure R2
R2>enable
R2#configure terminal
R2(config)#interface serial 0/0/0
R2(config-if)#encapsulation frame-relay
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#interface serial 0/0/0.101 point-to-point
R2(config-subif)#ip address 192.168.1.246 255.255.255.252
R2(config-subif)#frame-relay interface-dlci 101
R2(config-subif)#exit
R2(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.245

10. configure R3
R3>enable
R3#configure terminal
R3(config)#interface serial 0/0/0
R3(config-if)#encapsulation frame-relay
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#interface serial 0/0/0.101 point-to-point
R3(config-subif)#ip address 192.168.1.250 255.255.255.252
R3(config-subif)#frame-relay interface-dlci 101
R3(config-subif)#exit
R3(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.249
R3(config)#

11. configure R4
R4>enable
R4#configure terminal
R4(config)#interface serial 0/0/0
R4(config-if)#encapsulation frame-relay
R4(config-if)#no shutdown
R4(config-if)#exit
R4(config)#interface serial 0/0/0.101 point-to-point
R4(config-subif)#ip address 192.168.1.254 255.255.255.252
R4(config-subif)#frame-relay interface-dlci 101
R4(config-subif)#exit
R4(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.253
R4(config)#

12. Router(config)#interface serial 0/0/0 Enter in interface mode
Router(config-if)#encapsulation frame-relay
Turns on Frame Relay encapsulation with the default
encapsulation type of cisco
Router(config-if)#frame-relay lmitype {ansi | cisco |
q933a}
Depending on the option you select, this command sets
the LMI type to the ANSI standard, the Cisco standard,
or the ITU-T Q.933 Annex A standard.
Router(config-if)#frame-relay interface-dlci 110
Sets the DLCI number of 110 on the local interface and
enters Frame Relay DLCI configuration mode
Router(config-fr-dlci)#exit Returns to interface configuration mode
Router(config-if)#frame-relay map ip 192.168.100.1 110
broadcast
Maps the remote IP address (192.168.100.1) to the local
DLCI number (110). The optional broadcast keyword
specifies that broadcasts across IP should be forwarded
to this address. This is necessary when using dynamic
routing protocols.

13. Router(config-if)#no frame-relay inverse
arp
Turns off Inverse ARP.
Router#show frame-relay map Displays IP/DLCI map entries
Router#show frame-relay pvc Displays the status of all PVCs configured
Router#show frame-relay lmi Displays LMI statistics
Router#clear frame-relay counters Clears and resets all Frame Relay counters
Router#clear frame-relay inarp
Clears all Inverse ARP entries from the map
table
Router#debug frame-relay lmi
Used to help determine whether a router
and Frame Relay switch are exchanging LMI
packets properly
