    Description

      Overview:
      ---------
      No L3 ping connectivity between VMs caused by Local FIB entry creation failed due to missing prefix-to-interface entry

      Steps:
      ------

      • Created 3 networks (1.1.1.0/24, 2.2.2.0/24, 3.3.3.0/24) and router
      • Connected networks to router
      • Created 6 VMs, 2 on each network
      • Checked ping connectivity from 2.2.2.11 to 1.1.1.11

      Expected:
      ---------

      • Ping pass

      Actual:
      -------

      • Ping doesn't pass

      Root cause (after investigated by Tali Ben-Meir):
      -------------------------------------------------
      Local FIB entry creation failed due to missing prefix-to-interface entry

      The entry is eventually written, but not fast enough for the vrfEntryListener to see it
