we are designing our new datacenter and will probably use Cumulus Linux. As the datacenter used by multiple tenants (up to 500), we would like to use the VRF feature for secure network separation.
In the Cumulus documentation I've read, that there is a limitation of 64 VRF-Instances per switch. On some slides I've read that the limit depends on hardware capabilities.
Does someone know the definitive limit for Tomahawk based switches (esp. the Edgecore AS7712-32X)?
If the limit really is 64 VRF-Instances, are there any other suggestions to separate the networks?

We have increased the number to 256 in the latest release. I'll notify our documentation team to update the documentation.
This however will still not be enough if you need 500. Perhaps we can help you with the design or a workaround. Could you explain how you are running into the limitations on a single box and can you provide more details on the design?
