Extraroute not reachable from DC-GW to compute when tep is deleted on another compute

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Medium
    • Resolution: Done
    • Affects Version/s: None
    • Fix Version/s: None
    • Component/s: ipv6service
    • Labels:
    • Environment:

      3 node cluster with 2 computes.

      Description

      Traffic from DC-GW to extraroute connected to VM on compute-0-1 not reachable when vxlan tep is deleted on compute-0-2.

      Test Case:

      ========

      ->Configure 8 dualstack networks and 16 VMs and 2 routers. Two computes have one VM for each of the 8 networks. Attach 4 dualstack networks to each router

      ->Configure BGP, 2 VPN instances .

      ->Attach routers to VPN instances.

      ->Configure extra routes with four VMs as nexthops for both the routers.

      ->Verify reachability between DCGW and extraroute.

      ->Delete tep ip on compute2.

      Observation:

      Routes of VMs and extraroutes originating from compute2 shoudl be withdrawn -OK

      Extraroute should be reachable from DC-GW through compute-0-1-NOK

      Issue:

      Table 20 entries matching the extra route labels for both ipv4 and ipv6 are removed on compute0-1 due to which the traffic is lost.
