I've got this to work. Try using MAC addresses instead of IP in your trex_cfg.yaml
- port_limit : 2
version : 2
low_end : false
interfaces : ["3b:00.0", "3b:00.1"]
port_info :
- src_mac : b8:59:9f:xx:xx:xx
dest_mac : b8:59:9f:yy:yy:yy
- src_mac : b8:59:9f:xx:xx:xx
dest_mac : b8:59:9f:yy:yy:yy
(replace xx and yy)
I use python client code that constructs IPv6 packets using scapy, there's some
other trick for using IPv4 pcap files if that's what you use, google will help
there. I also use static ipv6 neighbors in VPP to point back to trex, but I
don't know if that's needed.
Thanks,
Chris.
