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. If the next hop IP is expected and the ARP of that next hop IP is expected, why are packets leaving out an unexpected interface?
Another route to the destination from a routing protocol with a lower distance? What does "show ip route [destination]" look like? -- Jay Hennigan - jay () west net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
