Wuxp, The first thing is to validate your claim that nothing sent from the VM when VPP is restarted. Start tcpdump and watch nothing is sent from the VM. I assume it happens all the times as supposed to once in a blue moon. If that is validated, I’d like to see your qemu startup command to see

Re: [vpp-dev] Bond interface won't respond ping #vnet #vpp

Anthony, L3 address should be configured on the bond interface, not the slave interface. If there is a switch in between VPP’s physical NICs and the VM, the switch should be configured to do the bonding, not the remote VM. Use show bond to check the bundle is created successfully between VPP an

Re: [vpp-dev] Bond interface won't respond ping #vnet #vpp

Dear Anthony, Please check the bond interface to see if the active slaves count has any positive number using show bond. Since you didn’t configure LACP on VM2, I believe you’ve not gotten any active slave in VPP. Your solution is to configure a bond interface in VM2 using mode 4 (I believe) if
