Configure Multicast Receiving Control

Network Requirements

Device1 configures multicast routing protocol.
Device2 enables IGMP snooping, configures multicast receiving control and applies to the corresponding port.
Multicast Server sends the multicast service packet; PC1 and PC2 can receive the multicast service packet.

Configuration Steps

Step 1: Device1 configures the interface IP address and enables the multicast route protocol. (omitted)

Step 2: Configure Device2.

#Create VLAN2 on Device2.

Device2#configure terminal
Device2(config)#vlan 2
Device2(config-vlan2)#exit

#Configure the link type of the port gigabitethernet0/2-gigabitethernet0/4 on Device2 as Access, permitting the services of VLAN2 to pass.

Device2#configure terminal
Device2(config)#vlan 2
Device2(config-vlan2)#exit
Device2(config)#interface gigabitethernet 0/2-0/4
Device2(config-if-range)#switchport access vlan 2
Device2(config-if-range)#exit

#Configure the link type of port gigabitethernet0/1 on Device2 as Trunk, permitting the services of VLAN2 to pass; PVID is configured as 1.

Device2(config)#interface gigabitethernet 0/1
Device2(config-if-gigabitethernet0/1)#switchport mode trunk
Device2(config-if-gigabitethernet0/1)#switchport trunk allowed vlan add 2
Device2(config-if-gigabitethernet0/1)#switchport trunk pvid vlan 1
Device2(config-if-gigabitethernet0/1)#exit

#Enable IGMP snooping.

Device2(config)#ip igmp snooping
Device2(config)#ip igmp snooping vlan 2

#Configure multicast receiving control policy profile1, permits to add multicast group 224.1.1.1 and apply to port gigabitethernet0/2.

Device2(config)#ip igmp profile 1
Device2(config-igmp-profile)#permit 224.1.1.1
Device2(config-igmp-profile)#exit
Device2(config)#interface gigabitethernet 0/2
Device2(config-if-gigabitethernet0/2)#ip igmp filter 1
Device2(config-if-gigabitethernet0/2)#exit

#Configure multicast receiving control policy profile2, preview multicast group 224.1.1.1 and apply to port gigabitethernet0/3.

Device2(config)#ip igmp profile 2
Device2(config-igmp-profile)#preview 224.1.1.1
Device2(config-igmp-profile)#exit
Device2(config)#interface gigabitethernet 0/3
Device2(config-if-gigabitethernet0/3)#ip igmp filter 2
Device2(config-if-gigabitethernet0/3)#exit

#Configure multicast receiving control policy profile3, refuse adding to multicast group 224.1.1.1 and apply to port gigabitethernet0/4.

Device2(config)#ip igmp profile 3
Device2(config-igmp-profile)#permit all
Device2(config-igmp-profile)#deny 224.1.1.1
Device2(config-igmp-profile)#exit
Device2(config)#interface gigabitethernet 0/4
Device2(config-if-gigabitethernet0/4)#ip igmp filter 3
Device2(config-if-gigabitethernet0/4)#exit

Step 3: Check the result.

#PC1, PC2 and PC3 send IGMPv2 member report packet to add to multicast group 224.1.1.1.

#View multicast member table of Device2.

Device2#show ip igmp snooping groups
IGMP Snooping Group Membership 
Total 2 groups

PC1 and PC2 can add to multicast group 224.1.1.1; PC3 does not add to multicast group 224.1.1.1.

# Multicast Server sends the multicast service packet with destination address 224.1.1.1.

PC1 and PC2 can correctly receive the multicast service packet; PC3 cannot receive the multicast service packet.

#After waiting for 10s, view the multicast member table of Device2 and multicast receiving control information of gigabitethernet0/3.

Device2#show ip igmp snooping groups

Device2#show multicast control interface gigabitethernet 0/3

After the preview time of port gigabitethernet0/3 arrives (after 10s), the group member entry is deleted; PC1 can correctly receive the multicast service packet; PC2 and PC2 cannot receive the multicast service packet.
