IBGP to OSPF examples

The network I'm working at is using IBGP and they want to move over to OSPF, I'm looking for some good examples and ideas for doing this. I'd like to lab some examples and have some documentation for a proposal that I need to submit for this.

Note: this is a large network data center type of environment using 6500 series devices.

Thank you,

are you using iBGP solely for the redistribution of the routes within your network?

if so, just configure the OSPF with the same networks (and optionally default route).

if you haven't changed the distance in BGP, then it will still be preferred.

you can cut over to OSPF leaving your BGP configuration intact by simply changing the distance under the 'router bgp' configuration.
