PPP Interface Command Set
ip mcast-stub fixed
Use the ip mcast-stub fixed command to allow forwarding of multicast traffic on a selected interface after
enabling multicast routing. Use the no form of this command to disable this mode.
Syntax Description
No subcommands.
Default Values
By default, this command is disabled.
Command History
Release 12.1
Command was introduced.
Functional Notes
Multicast routing must be enabled prior to setting ip mcast-stub fixed on the selected interface. Also, use
the ip igmp static-group <address> command (refer to
ip igmp on page
2507) to receive multicast traffic
without host-initiated Internet Group Management Protocol (IGMP) activity on the selected interface.
Otherwise, all host-initiated IGMP transactions will enter multicast routes on the router's interface involved
with IGMP activities.
Usage Examples
The following example enables multicast traffic forwarding and IGMP on the interface:
(config)#interface ppp 1
(config-ppp 1)#ip mcast-stub fixed
