Chapter 25 Configuring IGMP Snooping and MVR
Configuring IGMP Snooping
Configuring a Multicast Router Port
To add a multicast router port (add a static connection to a multicast router), use the
ip igmp snooping
vlan mrouter
global configuration command on the switch.
Beginning in privileged EXEC mode, follow these steps to enable a static connection to a multicast
router:
To remove a multicast router port from the VLAN, use the
no ip igmp snooping vlan
vlan-id
mrouter
interface
interface-id
global configuration command.
This example shows how to enable a static connection to a multicast router:
Switch#
configure terminal
Switch(config)#
ip igmp snooping vlan 200 mrouter interface gigabitethernet1/2
Switch(config)#
end
Configuring a Host Statically to Join a Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also statically configure
a host on an interface.
Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast
group:
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
ip igmp snooping vlan
vlan-id
mrouter
interface
interface-id
Specify the multicast router VLAN ID and the interface to the
multicast router.
•
The VLAN ID range is 1 to 1001 and 1006 to 4094.
•
The interface can be a physical interface or a port channel.
The port-channel range is 1 to 6.
Step 3
end
Return to privileged EXEC mode.
Step 4
show ip igmp snooping mrouter
[
vlan
vlan-id
] Verify that IGMP snooping is enabled on the VLAN interface.
Step 5
copy running-config startup-config
(Optional) Save your entries in the configuration file.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
ip igmp snooping vlan
vlan-id
static
ip_address
interface
interface-id
Statically configure a Layer 2 port as a member of a multicast
group:
•
vlan-id
is the multicast group VLAN ID. The range is 1 to
1001 and 1006 to 4094.
•
ip-address
is the group IP address.
•
interface-id
is the member port. It can be a physical
interface or a port channel (1 to 6).
Step 3
end
Return to privileged EXEC mode.
