Lets analyze one example and I will explain where I am coming from
OSPF into EIGRP
route-map O-E deny 10
match tag 90 (ensures that any route tag anywhere else that
matches 90 will not be redistributed)
!
route-map O-E permit 20
match tag 110 (If I have tagged this elsewhere match it, for
example the E-O route-map)
set tag 110 (ensure the tag remains and is not overwritten to
allow me to make decisions elsewhere is needed)
!
route-map O-E permit 25
match tag 120 (If I have tagged this elsewhere match it)
set tag 120 (ensure the tag remains and is not overwritten to
allow me to make decisions elsewhere is needed)
!
route-map O-E permit 30
set tag 90 (anything else left must be EIGRP so tag it so I can
use the tag elsewhere to make decisions)
If I am wrong in my logic please correct me.

Hi jason, I don't have access to the work book right now, but I
would suggest there is something omiss with your o-e route map...
Please correct if I'm wrong!
You start by denying tag 90, good, no eigrp going in to eigrp.
You then match ospf tag, and reset ospf tag? Liitle unsure on this,
wouldn't expect you to have ospf routes already tag as ospf routes
within ospf, but can see is possible. Usually expect this as a
catch all last entry with out the match command. Expect you may
have two ospf islands for example..
You then pass through rip, all fine.
But you then at the bottom of your route map, match everything else
known in ospf, and tag it as eigrp?? I would expect this to be
where you set tag 110...
Same concern on your e-o route map

I really appreciate your feedback as to whether the approach is
good and whether or not I should of done things differently.
Thanks

I'm in the class just now. I will have to read through the lab and
your solution to see.
Are there any loops in the network? If not, your solution must be OK.

Hey guys can you confirm whether my route-map works and ensures not
loops could form. The DSG has allot less configuration but I know
Marko has mentioned in his lectures that tags just ensure that
loops cannot for even if routing protocols have mechanisms to
prevent them. (Marko, I hope I have this right and if not I am sure
you will correct me :P )
Redistribution and ensure that there is no LOOPs
