Hi, I am trying to duplicate traffic in the following manner:
-------------------------------------------- VPP -------------------------------------------- [Physical DPDK Interface] <<--[ *PROBE* ]-- [AF_PACKET host-interface] ------------------------------------------------------------------------------------------------ Where Probe is a tun or VETH pair (unsure yet). The reason being, is that I am trying to analyze packets containing iOAM information without losing the production packets and routing. At the decapsulation node, VPP should remove all telemetry data prior to leaving the iOAM domain, so sniffing the DPDK interface is not an option. As a side note, this removal is not working either.... The flowprobe plugin seems to do something similar, but adds IPFIX to the traffic, which is not desired. I would like to copy the traffic and forward it to both the DPDK and probe interfaces. Any ideas would be appreciated. Regards, Mauricio
