Basic MCT configuration
This section describes how to set up a basic MCT configuration. Figure 101 shows a basic MCT
topology, which applies to Layer 2 and Layer 3. MCT can also be supported with VRRP or VRRP-E.
Refer to “MCT for VRRP or VRRP-E” on page 857.

MCT configuration considerations
• When running STP, the STP state should be the same on both cluster devices. For additional
information on running STP with MCT, refer to “STP/RSTP” on page 850.
• One ICL can be configured per device, and a device can be in only one cluster.
• The software version in both cluster devices must be exactly the same for the cluster to
function.
• An ICL port should not be an untagged member of any VLAN. An ICL is preferably a static trunk
that provides port level redundancy and higher bandwidth for cluster communication.
• ICL ports must be part of MCT VLANs and session VLANs.
