SROS Command Line Interface Reference Guide ATM Sub-Interface Config Command Set

ip mcast-stub helper-enable

Use the ip mcast-stub helper-enable command to assign the ip mcast-stub helper-address as the

IGMP-Proxy. Use the no form of this command to disable.

Syntax Description

No subcommands.

Default Values

By default, this command is disabled.

Command Modes

(config-atm 1.1)# ATM Sub-Interface Configuration Mode required

Functional Notes

This command is used in IP multicast stub applications in conjunction with the ip mcast-stub

helper-address, ip mcast-stub upstream, and ip mcast-stub downstream commands. When enabled,

the interface becomes a helper forwarding interface. The IGMP host function is dynamically enabled and

the interface becomes the active upstream interface, enabling the router to perform as an IGMP proxy.

See

ip mcast-stub helper-address <ip address> on page 290, ip mcast-stub downstream on page 679, and

ip mcast-stub upstream on page 681 for more information.

Usage Examples

The following example sets the helper-address as the IGMP-Proxy:

(config-atm 1.1)#ip mcast-stub helper-enable

1 2 ... 675 676 677 678 679 680 681 682 683 684 685 ... 940 941
