Hi neale, 'failed' means this : DBGvpp# ping 192.168.153.130
Statistics: 300 sent, 0 received, 100% packet loss what I know is in'run_ping_ip46_address', L598 got the wrong event_type I'm not running with multiple worker threads. My two vpp is in two 14.04 ubuntu,The two host interfaces are in the two VPP. The two interfaces connect directly.

The trace shows an echo-reply packet was received, matched against and outstanding request and punted. If you are running with multiple worker threads, you’ll need to include; https://gerrit.fd.io/r/#/c/6736/ the difference in the FIB output from 17.04 to 17.01 is not an error, it’s just that the rewrite string on the adjacency is no longer pretty printed/decoded.
