Two virtual machines located in separate virtual networks cannot communicate with one another.
Which two troubleshooting steps would help identify the problem?
Contrail network policy exchanges routes between virtual networks and must include rules that allow traffic between them; without an explicit allow rule, the flow is unresolved or short and its packets are dropped. Capturing traffic with tcpdump on a VM’s tap interface verifies whether traffic is entering or leaving the VM-side interface, helping isolate the failure point.
