BGP and EIGRP redistribution issue

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 .

BGP and EIGRP redistribution issue

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.

Re: BGP and EIGRP redistribution issue

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.
