ip mcast-stub downstream
Use the
ip mcast-stub downstream
command to enable multicast forwarding and IGMP (router mode) on
an interface, and to place it in multicast stub downstream 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 upstream
commands. Downstream interfaces connect to segments
with multicast hosts. Multiple interfaces may be configured in downstream mode; however, interfaces
connecting to the multicast network (upstream) should not be configured in downstream mode. Interfaces
configured as downstream should have the lowest IP address of all IGMP-capable routers on the
connected segment in order to be selected as the designated router and ensure proper forwarding. See
ip mcast-stub helper-address <ip address>
on page 642 for more
information.
Usage Examples
The following example enables multicast forwarding and IGMP on the interface:
ProCurve(config)#
interface ethernet 0/1
ProCurve(config-eth 0/1)#
ip mcast-stub downstream
