Are you seeing issues with the traffic flow on the switch? Any further information on the status of the OSPF environment would be helpful. A diagram of your physical network.

It looks like you have the 192.168.100.0 /24 and 192.168.255.32 /28 subnets learned by OSPF protocol. The rest are directly connected or static default route.

If you could be more specific about how this is affecting you overall network, then we could look into what options we have for a resolution.

Hope this helps,

OSPF cost is shown with numbers on right picture

ASA5510-1 and ASA5510-2 are not in active/standby or active/active mode, so i have to use ospf.
I used static route with AD 200 which is more then AD of OSPF.
Default routes are originated on cisco 2911 and are announced to ASA. According to ospf database, they are announced to Dell 7024 stack. 
When I added loopback on cisco 2911, strange thing has occured; route appeared in routing table of each device in the network except in dell 7024. Besides, this route disappeared
