Hi Abhishek, Are you still able to ping when the agent is not running? Did you try using "dropstats" to see if there are any drops inside vrouter? Are you seeing any checksum errors go up on the receiver of the ping (using netstat)?

Do we need to make changes in contrail-vrouter-agent code regarding this? Please help regarding this. Thanks [https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif]
