Hi Cagri,

External eigrp routes' AD is 170. So eigrp prefers the routes with AD 90,
not the external routes coming from OSPF or RIP (AD 170).

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.
