illustrates a deployment with clustering over the WAN.
Figure 2-17
Clustering Over the WAN
The following guidelines and considerations apply to deployments with clustering over the WAN:
•
The network deployment supports highly available, converged Visible and Private Networks. The
ICM Central Controller's Private traffic and Visible (Public) traffic are isolated and converge on
different edge devices.

•
WAN considerations for communications between the two Data Centers may include an
Multiprotocol Label Switching (MPLS) backbone with VPN routing/forwarding tables VRFs.
