It does not matter which activities you perform first. The only principle I
want you to put in mind when perforning redistribution is the following. For
example when you enter the following sequence of commands;

router rip
redistribute ospf X metric 2

the OSPF redistribution command within RIP causes the router to look into
the routing table and pick up all entries that have been learnt by OSPF
(both IA, E1&2, N1&2), and then all the networks that the interfaces on
which OSPF has been enabled are also picked up for advertisement by RIP. So
two things happen in the nutshell;

(1) pick up all entries found in the routing table learnt through the
routing process redistributed.
(2) check for the interfaces on which the redistributed routing process is
enabled and then advertise the prefixes that these interfaces are connected
to.

These same activities happen whenever you perform redistribution on most
routing protocols.

Hope this was informative?
