We have a Nexus 3064 that is setup with partial BGP tables and is routing based on that.


I've done a show ip bgp for an IP of interest and it has an expected next hop IP. I show ip arp on that next hop IP and it has the expected interface.


However, sFlows show the packets leaving on a different interface, the one that would carry the default route for routes not otherwise known.

What does traceroute to that IP show?
