ip mcast-stub upstream
Use the
ip mcast-stub upstream
command to enable multicast forwarding on an interface and place it in
multicast stub upstream mode. 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
and
ip mcast-stub downstream
commands. When enabled, the interface becomes a
candidate to be a helper forwarding interface. If chosen as the best path toward the helper address by the
router's unicast route table, the IGMP host function is dynamically enabled and the interface becomes the
active upstream interface, enabling the router to perform as an IGMP proxy. Though multiple interfaces
may be candidates, no more than one interface will actively serve as the helper forwarding interface. Refer
to
ip mcast-stub helper-address <ip address>
on page 423 and
more information.
Usage Examples
The following example enables multicast forwarding on the interface:
ProCurve(config)#
interface frame-relay 1.16
ProCurve(config-fr 1.16)#
ip mcast-stub upstream
