The IGMP proxy offers a mechanism for multicast forwarding based only on IGMP membership information. The router must decide about forwarding packets on each of its interfaces based on the IGMP membership information. The proxy creates the forwarding entries based on the membership information and adds it to the multicast forwarding cache (MFC) in order not to make the forwarding decision for subsequent multicast packets with same combination of source and group. CLI Examples The CLI component of the Dell switch allows the end users to configure the network device and to view device settings and statistics using a serial interface or telnet session. Example #1: Configuring IGMP Proxy on the Router This command enables the IGMP Proxy on the router. To enable IGMP Proxy on the router no multicast routing protocol should be enabled and also multicast forwarding must be enabled on the router. Use these commands from the Interface mode: console#configure ip routing ip multicast ip igmp interface vlan 15 ip igmp-proxy Additional configuration options are available for the igmp-proxy command: reset-status unsolicited-report-interval Press Enter to execute the command. Reset All the proxy interface status parameters. Configure IGMP Proxy unsolicited report interval. The value of the unsolicited report interval can range from 1 to 260 seconds. The default is 1 second. Use this command from the Interface mode. Example #2: View IGMP Proxy Configuration Data You can use various commands from Privileged EXEC or User EXEC modes to show IGMP proxy configuration data. • Use the following command to display a summary of the host interface status parameters. It displays the parameters only when IGMP Proxy is enabled. console#show ip igmp-proxy Interface Index vlan 15 Admin Mode Enabled Operational Mode Disabled Multicast 145

The IGMP proxy offers a mechanism for multicast forwarding based only on IGMP membership
information. The router must decide about forwarding packets on each of its interfaces based on the
IGMP membership information. The proxy creates the forwarding entries based on the membership
information and adds it to the multicast forwarding cache (MFC) in order not to make the forwarding
decision for subsequent multicast packets with same combination of source and group.
CLI Examples
The CLI component of the Dell switch allows the end users to configure the network device and to view
device settings and statistics using a serial interface or telnet session.
Example #1: Configuring IGMP Proxy on the Router
This command enables the IGMP Proxy on the router. To enable IGMP Proxy on the router no multicast
routing protocol should be enabled and also multicast forwarding must be enabled on the router. Use
these commands from the Interface mode:
console#configure
ip routing
ip multicast
ip igmp
interface vlan 15
ip igmp-proxy
Additional configuration options are available for the igmp-proxy command:
<cr>
Press Enter to execute the command.
reset-status
Reset All the proxy interface status
parameters.
unsolicited-report-interval
Configure IGMP Proxy unsolicited report
interval.
The value of the unsolicited report interval can range from 1 to 260 seconds. The default is 1 second. Use
this command from the Interface mode.
Example #2: View IGMP Proxy Configuration Data
You can use various commands from Privileged EXEC or User EXEC modes to show IGMP proxy
configuration data.
•
Use the following command to display a summary of the host interface status parameters. It displays
the parameters only when IGMP Proxy is enabled.
console#show ip igmp-proxy
