Step 1:
Configure the frame relay switch a Cisco 2600 is used in this example:
In global config mode type...
1. frame-relay switching
2. Configure the serial interfaces for frame relay
interface Serial1/0
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
serial restart-delay 0
clock rate 56000
no frame-relay inverse-arp
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 102 interface Serial1/1 201
frame-relay route 103 interface Serial1/2 301
!
!
interface Serial1/1
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
serial restart-delay 0
clock rate 56000
no frame-relay inverse-arp
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 201 interface Serial1/0 102
frame-relay route 701 interface Serial1/2 107
!
!
interface Serial1/2
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
serial restart-delay 0
clock rate 56000
no frame-relay inverse-arp
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 107 interface Serial1/1 701
frame-relay route 301 interface Serial1/0 103
!
This is the end of the FRAME RELAY SWITCH CONFIG
I will now configure each router in the frame relay network.
R1:
1. Go under the serial interface and configure the following...
interface Serial1/0
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
serial restart-delay 0
2. Pay close attention to the configuration, notice no IP address has been configured and encapsulation has been configured.
Note: In this particular lab sub interfaces will be configured as Point-To-Point.
3. Configure the sub interface to support the DLCI being used. A best practice is to configure the sub interface with the DLCI number. For example DLCI 102 will be configured as interface s1/0.101 point-to-point.
!
interface Serial1/0.102 point-to-point
ip address 10.0.0.1 255.224.0.0
frame-relay interface-dlci 102
!
interface Serial1/0.103 point-to-point
ip address 10.32.0.1 255.224.0.0
frame-relay interface-dlci 103
I will repeat steps 1-3 on R2 and R3.
R2:
!
interface Serial1/0
no ip address
encapsulation frame-relay
serial restart-delay 0
!
!
interface Serial1/0.201 point-to-point
ip address 10.0.0.2 255.224.0.0
frame-relay interface-dlci 201
!
interface Serial1/0.701 point-to-point
ip address 10.64.0.1 255.224.0.0
frame-relay interface-dlci 701
R3:
interface Serial1/0
no ip address
encapsulation frame-relay
serial restart-delay 0
!
!
interface Serial1/0.107 point-to-point
ip address 10.64.0.2 255.224.0.0
frame-relay interface-dlci 107
!
interface Serial1/0.301 point-to-point
ip address 10.32.0.2 255.224.0.0
frame-relay interface-dlci 301
Note: Each sub interface is in it's own subnet and the IP address much match each point-to-point sub interface.
