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

If my post was useful accept solution and/or give kudos.

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.

Thanks John for sharing your experience.
Have you compared with the Lab guide (configuration) on this Lab?
https://community.arubanetworks.com/community-home/digestviewer/viewthread?GroupId=565&MessageKey=bca5bc66-ab2d-46e9-b2f5-675af866d83b&CommunityKey=aa40c287-728e-4827-b062-5eff4ed6410b&tab=digestviewer&ReturnUrl=%2fcommunity-home%2fdigestviewer%3fcommunitykey%3daa40c287-728e-4827-b062-5eff4ed6410b%26tab%3ddigestviewer
May be worth sharing your configuration so that others may take a look.

Have tried this L2 setup with 10.06, 10.07 and on EVE-NG, GNS3 and even plain on ESXi and when it is started up CX1 becomes the root as it is configured with the priority to become root and all other ports configure themselves correctly and the setup is stable until you try to ping from VPC1 to VPC2. First ping is OK but after that a gratuitous ARP is looping around and also the STP starts converging. MAC address of VPC1 also moves from the correct port 1/1/3 to 1/1/1. I have tried both RSTP and MSTP but same result.
Only when I replace the CX devices with other devices (tried Aruba VMC) in the same setup does it work correctly.
Thanks,
John
