I agree with Rick, there's insufficient information to provide a detailed answer, but I suspect what you're trying to accomplish is to share routes between your Cisco router running EIGRP and an Alcatel that is running OSPF.
If so, at a high level, you would want to run OSPF on your Cisco router and have it become an OSPF neighbor of your Alcatel. Once you accomplish that, your Cisco router will "know" both your EIGRP and OSPF routes. You can then redistribute routes between the two routing protocols.
Technically, such route redistribution isn't difficult, but logically you need to take care. The latter often requires a good deal of information to understand your network topology and your routing requirements.
If you've never done route redistribution, and your network is anything but simple, you might want to retain a network consultant to assist you.
