Hi Mechthild,

It looks like you are running version 21.06 of VPP. This patch was merged last 
month and may resolve the issue - 
https://gerrit.fd.io/r/c/vpp/+/34815.
 Can you try applying that patch to your build?

Let me know if that helps.

Thanks,
-Matt

Hi all,

We are using VPP on two nodes and run VRRP on them. This works fine as long as 
we use one VLAN. But if we configure VRs in different VLANs we see strange 
behavior: Every 4 seconds, the backup  VRRP VR shortly changes to master and 
sends an advertisement message to the master and then it changes back to master.

The symptom:
# while true; do date; vppctl show vrrp vr | grep state; echo; sleep 1; done

Re: [vpp-dev] Facing issue with forming packets in dpdk-testpmd.

This is a question for https://mails.dpdk.org/listinfo/users
We are mostly using trex but still, there is a --tx-ip option documented in 
https://doc.dpdk.org/guides/testpmd_app_ug/run_app.html#testpmd-command-line-options
