IGMP and MLD Snooping

Snooping can be configured globally or at the VLAN level. Each cluster device in the MCT VLAN can be configured as active or passive. There is no restriction for cluster devices to run active-active or passive-passive configurations.

The following examples show configuration commands for the VLAN level (IGMP and MLD), the global level (IGMP and MLD), and for PIM-SM and PIM6-SM.

• VLAN level (IGMP)

  device(config)# vlan 100
  device(config-vlan-100)# multicast active/passive
  

• VLAN level (MLD)

  device(config-vlan-100)# multicast6 active/passive
  

• Global level (IGMP and MLD)

  device(config)# ip multicast active/passive
  device(config)# ipv6 multicast active/passive
  

• PIM-SM snooping (configured only on a VLAN and requires IGMP snooping to run in passive mode)

  device(config)# vlan 100 
  device(config-vlan-100)# multicast passive
  device(config-vlan-100)# multicast pimsm-snooping

• PIM6-SM snooping (configured only on a VLAN and requires MLD snooping to run in passive mode)

  device(config)# vlan 100 
  device(config-vlan-100)# multicast6 passive
  device(config-vlan-100)# multicast6 pimsm-snooping
