SROS Command Line Interface Reference Guide Tunnel Configuration 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.
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 unit to perform as an IGMP proxy. Refer
ip mcast-stub helper-address <ip address> ip mcast-stub downstream
to on page 423, on page 1172, and
ip mcast-stub upstream
on page 1175 for more information.
Usage Examples
The following example sets the helper address as the IGMP proxy:
ProCurve(config)#interface tunnel 1
ProCurve(config-tunnel 1)#ip mcast-stub helper-enable
