You can create an ARP entry manually for an IP address. Thus you can set up a MAC for the IP you want to use as the gateway IP to bypass the ARP request sequence.
DBGvpp# set ip arp ? set ip arp set ip arp [del] <intfc> <ip-address> <mac-address> [static] [count <count>] [fib-id <fib-id>] [proxy <lo-addr> - <hi-addr>] Example: set ip arp fib-id 3 loop0 6.0.0.10 0606.0606.0606 This will not work in a "real" setup unless the MAC really matches that of the remote gateway. It is OK if you just want to see packet forwarded via VXLAN tunnel and the receiver does not care about DMAC, etc. Regards, John -----Original Message----- From: Ivan Kelly [mailto:i...@midokura.com] Sent: Thursday, November 03, 2016 5:34 PM To: John Lo (loj); vpp-dev Subject: Re: [vpp-dev] ip4-lookup to vxlan and vice versa Oops, forgot to include list.
