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.

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...

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.
