eigrp

[M.bo]

I have the following topology 

Nexus switch N1 connected to  nexus N2 using ospf

N1 connected to router asr using eigrp

N2 connected to router asr using eigrp

I can see ip of nexus 1 on nexus 2 under the eigrp topology command, how can I block this route only( n1 ip)  from reaching n2 under the eigrp??

We do not yet have enough information to be able to give good advice. You tell us that N1 and N2 connect to asr router. Is it the same asr router? Or if they connect to separate asr routers, do these routers run EIGRP and exchange routes with each other? 

Can you provide details Of N1 and N2 OSPF (what interfaces does it use, what is the IP of those interfaces, how is OSPF configured, is there redistribution of EIGRP into OSPF, what networks does OSPF advertise)? Can you provide details of N1 and N2 EIGRP (what interfaces does it use, what is the IP of those interfaces, how is EIGRP configured, is there redistribution of OSPF into EIGRP, what networks does EIGRP advertise)? Can you post the entry in the EIGRP topology table?
