Hi
I would shortly have Three sites connected with each other
Site_A connected to Site_B
Site_A connected to Site_C
Site_B connected to Site_C
All are connected via Wimax with Ethernet Interface 10/100 ( 6MB for each connection )
Is following OSPF config Ok in terms of redundancy and loop free
If one of the link goes down still there shoud be full reachability
Site_A connected to Site_B
Site_A : 192.168.1.1/30
Site_B : 192.168.1.2/30
Site_A connected to Site_C
Site_A : 192.168.1.4/30
Site_C : 192.168.1.5/30
Site_B connected to Site_C
Site_B : 192.168.1.7/30
Site_C : 192.168.1.8/30
SITE_A
router ospf 1
network 192.168.1.1 0.0.0.0 area 0
network 192.168.1.4 0.0.0.0 area 0
network 10.10.10.0 0.0.0.255 area 0
SITE_B
router ospf 1
network 192.168.1.2 0.0.0.0 area 0
network 192.168.1.7 0.0.0.0 area 0
network 10.10.20.0 0.0.0.255 area 0
SITE_C
router ospf 1
network 192.168.1.5 0.0.0.0 area 0
network 192.168.1.8 0.0.0.0 area 0

Hello Saquib,
configuration is fine but IP addressing should be reviewed:
when using /30 subnets, each uses 4 addresses
192.168.1.0/30 - 192.168.1.0 base address, 192.168.1-2 usable addresses; 192.168.1.3 broadcast
192.168.1.4/30 192.168.1.4 base address, 192.168.5-6 usable addresses; 192.168.1.7 broadcast
192.168.1.8/30 192.168.1.8 base address, 192.168.9-10 usable addresses; 192.168.1.11 broadcast
hope to help
