Configuring multicast client interfaces
A multicast client interface is an IP-enabled ATM PVC across a DSL interface to a CPE
router such as a CellPipe®.
Overview of multicast client
ip-options
settings
In addition to the ATM and IP options needed to configure a terminating PVC, the
following parameters, shown with default values, are used to enable IP multicast on a
client interface:
[in CONNECTION/"":ip-options]
multicast-allowed = no
multicast-rate-limit = 100
multicast-group-leave-delay = 0
multicast-group-leave-delay-msec = 0
multicast-service-profile = ""
multicast-max-groups = 0
Parameter
RADIUS attribute
Setting
multicast-allowed
Ascend-Multicast-
Client (155)
Enable/disable handling of IGMP requests and
responses on the interface. The system does not forward
multicast traffic on the basis of this setting.
multicast-rate-
limit
Ascend-Multicast-
Rate-Limit (152)
The rate at which the Stinger IP2000 accepts multicast
packets from clients on the interface. For example, if
you set the rate to 5, the system accepts one packet
every 5 seconds from multicast clients on the interface.
Any subsequent packets received within that 5-second
window are discarded.
The default value of 100 disables multicast forwarding
on the interface—the Stinger acts as a forwarder and
handles IGMP packets, but does not accept packets from
clients or forward multicast packets from the MBONE
router. To enable multicast forwarding on the interface,
you must set the rate to a number less than 100.
