Are you sure of what you are saying?
The way I know it, correct me if I'm wrong, is the following:
* you "redistribute connected" when :
1) you are told not to use the network statement to advertise the connected network, or
2) when in OSPF you are not told which area to use, or, always in OSPF,
3) when you are asked to advertise a stub network using the associated mask and you cannot configure "ip ospf network point-to-point"
When you do that you usually redistribute connected with a route-map that exactly specifies the connected route.
redistribute connected route-map Loopback0-only for example
That also means you are automatically denying from the redistribution all the other connected networks.
* now assume you need to redistribute into that same protocol a different one. Ex:
router ospf 1
redistribute connected route-map Loopback0-only
redistribute eigrp .... <<<<<
Eigrp, in the example, is surely running on some of your connected routes,
well these routes won't be redistributed in OSPF. Why?
Because you are denying them with the "redistribute connected route-map Loopback-only" route-map.
You have to change your "connected" route-map to include the connected routes where you run EIGRP

Subject: Re: when do we need to redistribute connected
Whenever you specify a route-map to the routing protocol being
redistributed, you
need to explicitly specify the connected subnet as well.
If they just redistribute without any route-map, the connected subnet where
that routing protocol is enabled get redistributed.
