Hi Group,

Trying to configure simple Frame-relay switch (hub and spoke). OSPF is also
enabled on spoke routers

FR-switch-----------------RTR-A(192.168.16.162)
    |
    |---------------------------RTR-B(192.168.16.161)

-------------------------Frame-relay switch
config---------------------------------------
FR_Switch#
FR_Switch#config t
FR_Switch(config)# frame-relay switching
FR_Switch(config)# exit
FR_Switch#
FR_Switch#config t
FR_Switch(config)# interface serial0/0
FR_Switch(config-if)#shutdown
FR_Switch(config-if)#encapsulation frame-relay cisco
FR_Switch(config-if)#frame-relay intf-type dce
FR_Switch(config-if)#frame-relay route 211 interface serial0/1 112
FR_Switch(config-if)#no shut
FR_Switch(config-if)#exit

FR_Switch#
FR_Switch#config t
FR_Switch(config)# interface serial0/1
FR_Switch(config-if)#shutdown
FR_Switch(config-if)#encapsulation frame-relay cisco
FR_Switch(config-if)#frame-relay intf-type dce
FR_Switch(config-if)#frame-relay route 112 interface serial0/0 211
FR_Switch(config-if)#no shutdown
FR_Switch(config-if)# exit
FR_Switch#write memory
FR_Switch#

----------RTR-A CONFIGURATION---------------------------------------
RTR-A#
RTR-A#config t
RTR-A(config)# interface serial0/0
RTR-A(config-if)#shutdown
RTR-A(config-if)#ip address 192.168.18.162 255.255.255.252
RTR-A(config-if)#encapsulation frame-relay cisco
RTR-A(config-if)#bandwidth 128000
RTR-A(config-if)#no shutdown
RTR-A(config-if)# exit
RTR-A#write memory
RTR-A#

Router OSPF
network 192.168.18.0

-------------------------RTR-B CONFIGURATION------------------------------

RTR-B#
RTR-A#config t
RTR-B(config)# interface serial0/0
RTR-B(config-if)#shutdown
RTR-B(config-if)#encapsulation frame-relay cisco
RTR-B(config-if)#bandwidth 128000
RTR-B(config-if)#ip address 192.168.18.161 255.255.255.252
RTR-B(config-if)#no shutdown
RTR-B(config-if)# exit

Router OSPF
network 192.168.18.0

Couple of doubt:
------------------------

The router are in the LAB environment, hence connected with DTE-dce cable
(as usual).

1) Do I need to configure the clock rate on frame-relay switch router or if
I configure clock rate on either on RTR-A or RTR-B ?

2) Concept - How OSPF will run between RTR-A and RTR-B

Thanks
Frog
