Hi All,
I am running into an routing issue in Nexus environment. please help if anyone know the issue. here is the simple diagram and I put some information in the diagram also.

here is the problem.
USER-1 able to reach vlan 10 SVI in SW-3 but unable to reach the vlan 10 SVI in SW-4. SW-3 has the user subnet in its BGP routing table. SW-4 use OSPF via peer link.
when I move the OSPF routing to dedicated link between SW-3 and SW-4, SW-4 still use OSPF to reach user subnet, and this time also working fine. this is normally we do. we use dedicated links for routing. but if we use layer3 peer-router, we can run the routing over peer link. but why it is not working in this case? when I shutdown the back to back vPC port-channel in SW-4, its working.
anyone has any idea? what is wrong here? I am using version 7.0(3)i7(6) -N9K-C9372PX-E
thanks
