i am trying to redistribute BGP routes into EIGRP . On the router the routes are correct and leaned via BGP and given preference
but when i check at Core switch the EIGRP is given preference .
I have tried to give redistributed BGP higher metric but even then EIGRP is the first choice for core switch
Can any help why this is happening and how i can solve the issue so that my core switch .

Hi Mohit,
Did you mena, you have EIGRP and BGP connection between router and core switch?. Can you give a gist about the topology?.
BTW, between different protocols, you need to tweak the admin distance to prefer and not the metrics. I assume you are receivign from iBGP (whcih is of admin distance 200) and EIGRP (whcih is admin distance of 170) and so EIGRP is preferred.

thanks nagendra .
our topology is like this . We are running EIGRP and BGP on one core Router and expecting Core switch to learn that route via EIGRP.
