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:
---------
Actual:
-------
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
