Layer 2 Multicast Snooping over MCT

To support multicast snooping over MCT, the ICL port uses MDUP to synchronize the following information between the cluster devices:

  • MAC-forward entries (mcache entries on MCT VLAN)
  • IGMP or MLD Join and Leave (control packets on MCT VLAN)
  • PIM-SM or PIM6-SM Join and Prune (control packets on MCT VLAN)
  • IGMP or MLD dynamic router ports on MCT VLAN
