  Cagri,
    This is a very complex question and there are some templates of howto approaches this in general and systematic way: do a search on Caslow (author ) and you will find some interesting links.
    I found the Doit2 have lots of complex redistribution between EIGRP-RIP-OSPF al together !!!
    In short , EIGRP have built in loop detect ( 90/170 ) that RIP do not .
   HTH,

  Hi all,

Is there a criteria to put tags and filter them while mutually
redistributing between two IGPs at two points ?

For example at a lab I see RIP<->OSPF distribution fully tagged and filtered
on both protocols, on the other lab EIGRP<->OSPF is not tagged at all and
not causing any loops. What is the point I am missing ? What about
EIGRP<->RIP in the same manner ?

I know question sounds a bit humble but I am really confused.
