L3VPN: IPv6 Datapath not working with DC-GW

XMLWordPrintable

    • Highest

      IPv6 Datapath not working with DC-GW

      1. Create N1 with S1(IPv4) and S2(IPv6).
      2. Create Port and boot VM
      3. Validate DC-GW and Local routes learned in both ODL and DC-GW
      4. Verify datapath for Both IPv4 and IPv6.

       Observations:

          1. Packet in flows hitting IPv4 path instead of IPv flow path. 

          2. Incorrect Source MAC address observed.
