Tom,
Just wanted to say I do do this in fact l first started up setting by ospf process id the same as my router so if R1 it would be router ospf 1, R2 router ospf 2, this of course got confusing so I started using 4 and then I started setting my alias to include it so that I always had it up and running pretty quick.
Do you have a sample of the tagging and route-maps, I'm a little bit of a visual guy and reading doesn't always stick in my head, I need to see and then test, hopefully it blows up, so I actually learn..
Thanks..

The advice on this thread has been great! Do whatever makes sense to you
and will make it easiest for you to see at a glance what is going on. I
would go further and say that, for the purposes of CCIE preparation, you
might want to form habits of using the same numbers for your EIGRP AS and
OSPF process (where these values are not prescribed for you).
For example, if your OSPF process is always 64 and your EIGRP AS number is
always 20, that makes troubleshooting your practice labs much easier than if
you choose different numbers on the fly and have to remember what number
stood for what. When using tagging and route-maps to prevent route feedback
when doing mutual redistribution, I like to tag the routes with the number I
associate with their source routing domain. This facilitates
troubleshooting somewhat.
Of course, you need to be prepared to deviate from your habit if ordered to
do so, but it's very helpful to have customary ways of doing things in
practice labs.
