Hello all I saw in https://www.mail-archive.com/[email protected]/msg15373.html , that trace-route is not implemented yet in OVS. I need to implement a more enhanced trace-route for vxlan overlay. As we use the OVS as a vTEP device I need to trace-route the actual data-path for a given vxlan-segment (since there are multi ecmp paths - this should traverse a specific path based on the source UDP port) This is done by transmitting a series an vxlan encapsulated packets with an incremental TTL , IP-destined to the remote vTEP. an intermediate device (which are generally traditional routers in the underlay) replies with ICMP ttl expired. 2 questions:
- How to initiate these packets transmission in the originating vTEP ? can I do it from the vTEP/ a local application ? - How the ICMP replies can be delivered/ if any to a local application that is connected to the vTEP via a TAP device ? Thanks and regards Avi
