here is my network topology:
i have a customer which is connected to my top of rack switch and my top of rack switch has 2x 10g LACP towards my both Cisco Nexus 3k and both of my Nexus 3k has VPC PEER link, here is customer router interface vlan config :
interface vlan542 IP address 192.168.20.1/30
then my customer will set 192.168.20.2/30 in own router and now we want to establish bgp from customer router towards n3k, but if we do this then bgp flap occur, because sometimes bgp request send to first n3k and sometimes send to second n3k, what is the solution for this? also i know one of the solutions is to connect my customer router directly to both of my n3k then establish 2 different bgp or form LACP or such things, but i want to know if we can find any solution in this senario. Thank you.
