About Multi-Chassis Trunk (MCT)

The following failure modes can occur for Layer 2 multicast over MCT.
Local CCEP down event:
• Outgoing traffic on local CCEP will now go through ICL and go out of remote CCEP.
• Incoming traffic on local CCEP will now ingress through remote CCEP, and then ingress through
ICL locally.
Local CCEP up event:
• Outgoing traffic on remote CCEP (after egressing through local ICL) will now start going out of
local CCEP.
• Incoming traffic from client through ICL (after ingressing on remote CCEP) will now switch back
to local CCEP (this is true only if the client trunk hashing sends the traffic towards local CCEP).
CCP (Cluster communication protocol) Down event:
• All related information (i.e. IGMP/MLD group, mcache, router port, static port, pim-sm
snooping entry) that was synced from the MCT peer will now be marked for aging locally.
