Testing latest 10.11.xx.xx version with EVE-NG aswell pnetlab and having the same issues John described. After the first ping from a vPC the gracious arp packages are looped. When not using vPCs but connect switches in a ring-topology i don't had this issue.

Hi ariyap
I jumped right to testing. And I'm running my test in EVE-NG Pro with 3 devices on 10.10.1000.
Spanning tree is still broken when I'm testing. The problem is packets are transmitted out on interfaces in blocking state.
Are you sure you have a loop free topology and packets are discarded out on interfaces in blocking?
Which hypervisor are you using?

I don't see this issue, i am using simulator version 10_10_1000

Is this still a limitation of the simulator or plan to work as expected at some point? Using latest 10.11 image for cx switch and can't pass normal traffic as expected.

HI John,
I'm seeing what could be similar behavior from the VPCS. We'll investigate and see where the issue is.

Hi Vincent,
Yes, I have looked at that guide and configured everything the same but no matter which STP I use it always fails when you start to ping from VPC1 to VPC2. I have use RPVST and MSTP but no difference. As I wrote when I started this thread, it works fine with a stable tree as long as you do not produce any packets on the VPC's. I do suspect something strange with the OVA's and wonder if the person that wrote the RPVST guide has send traffic from the VPC.
