As you create a second ospf process, you should redistribute those routes that
need to summaries
(using route map)and then just redistribute both ospf(100 and 200) process into
rip.
This to ensure that we will not over grow the new ospf process and also show th
e other that you try to achieve. Merely just redistribute the whole process int
o another is not a good solution.

If you want to see what's inside ospf 200, you can add a dummy interface
into there and issue the command "show ip ospf 200 database", it should help
to clear any possible confusions. You need at least one local network for
the command to show up anything.
