Catalyst Center Disaster 1+1+1

[aleopoldie]

Hello,

I have a question regarding the Catalyst Center Disaster 1+1+1 design (1 Catalyst Center in the main site, 1 Catalyst Center in the recovery site and 1 Witness VM). We can have L2 between the 2 x Datacenters.

I understand for a 3+3+1 design, we have 2 clusters, one on the main site and one on the secondary site.

But what about the 1+1+1 ? Do we have to configure a dedicated cluster of 1 appliance on the main site and another one in the recovery site ? Meaning 1 enterprise VIP for the main site and a different one for the recovery site ?

It means there would be only one Catalyst Center on the cluster of the main site and one Catalyst Center on the cluster of the recovery site. If I understand correctly ?

I checked the official documentation but that's not very clear...
