Hi

The internal distance of bgp on all routers is set to 109  (less than OSPF 110) but still routes are using ospf and not bgp although 'show ip route' should yield to the result shown in the attached document 'report'. all configurations are shown in the second document 'bgp topology'.

i need ur help any idea?

you want that route 131.108.255.0 /30 should use BGP for routing?

Use below mentioned configurations for four routers i hope issue will be solved and after doing this use
clear ip bgp *

R1
router bgp 333
no synchronization
bgp log-neighbor-changes
network 131.108.1.0 mask 255.255.255.0

neighbor ibgp remote-as 333
neighbor ibgp update-source Loopback0
neighbor 131.108.254.2 peer-group ibgp
neighbor 131.108.254.3 peer-group ibgp
neighbor 131.108.254.4 remote-as 333
