IGMP Proxy Configuration
The following procedure shows the basic steps for creation and configuring of an IGMP Proxy router.
IGMP Proxy configuration example
The following example, as illustrated in Figure 17-221 on page 253, configures the S-Series switch
identified as Unit 1, as the IGMP Proxy router, then configures port 1/0/48 as the IGMP Proxy port, and
then configures VLAN 2 as the IGMP Proxy VLAN and to include port 1/0/48. First, IP routing, multicast
forwarding, and IGMP must be enabled for the switch.
Step Command Syntax Command Mode Purpose
1 ip routing Global Config Enable routing on the switch.
2
ip multicast Global Config Enable multicast forwarding on the router.
Note: No multicast routing protocols can be enabled
on the router.
3
ip igmp Global Config Set the IGMP administrative mode to active in the router.
4
interface unit/slot/port Global Config Access the port that will forward IGMP Proxy control
data.
5
no shutdown Interface Config Enable the selected port.
6
routing Interface Config Enable routing for the selected port.
7
ip address ip_address
subnet_mask
Interface Config Assign an IP address and subnet mask to the selected port.
8
ip igmp-proxy Interface Config Designate the selected port as the IGMP Proxy port.
9
interface vlan vlan-id VLAN Create and/or access the designated VLAN.
10
untagged unit/slot/port VLAN Add the port configured earlier to the selected VLAN as
untagged.
11
ip address ip_address
subnet_mask
VLAN Assign an IP address and subnet mask to the selected
VLAN.
12
ip igmp-proxy VLAN Set the administrative mode of IGMP for the selected
VLAN to active.
