Hello,

Have  C3560 Software (C3560-IPSERVICES-M),

router ospf 1
log-adjacency-changes
redistribute connected subnets
passive-interface default
no passive-interface Vlan206
no passive-interface Vlan3734
network 173.21.206.0 0.0.0.255 area 0
network 173.21.231.52 0.0.0.3 area 0

#sh ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is 172.28.235.53 to network 0.0.0.0

173.21.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 173.21.231.52/30 is directly connected, Vlan3734
C 172.21.206.0/24 is directly connected, Vlan206
S* 0.0.0.0/0 [1/0] via 173.28.231.53

Remove passive-interface default command from the configuration which is preventing the ospf hello advertisements to be sent to the neighbor. Once done check the ospf neighborship between the routers.
