rVPC
Hey Wilder,
I hope that you are well.
We've found that the rVPC seems to use the same MAC address on the public interface of both the Master and Backup rVPC nodes - was this by design?
Kind regards,

Thanks for this information Wei,
It there a detailed design document which imcludes this kind of information for the redundant routers and VPCs?
My understanding is that they use VRRP, which *can* use a 'virtual MAC' but the primary MAC addresses of the public interface should be unique - with the last byte of the MAC address matching representing the Virtual Router Identifier.
I'd like to understand why this was implemented differently.
Kind regards,

Hi Paul,
CloudStack is designed like it. Not only RVR on VPC, but also RVR for isolated network, the MAC on public interface are the same on MASTER/BACKUP.
