Syntax
gmb user-data { mode-preference { multicast | unicast } | unicast-self-address self_ip_address }default gmb user-data
mode-preferenceno gmb user-data unicast-self-address
no
Removes the configured
self address of GGSN for unicast in the BMSC profile for user data of
MBMS user service.
defualt
Sets the user data
mode to unicast in the BMSC profile for user data of MBMS user service.
mode-preference { multicast | unicast }
Default: unicast
Specifies the preferred
mode of GGSN for receiving MBMS user service data.
multicast:
specifies the preferred mode as multicast for MBMS user service.
IMPORTANT:
Note that this multicast keyword
is not supported in this release.
unicast: specifies
the preferred mode as unicast for MBMS user service.
unicast-self-address self_ip_address
Specifies the GGSN’s
IP address for BMSC to use as the outer destination address for
the IP-in-IP tunnel to send multicast data, if the configured preferred
data mode is unicast.
self_ip_address must
be the IPv4 address in dotted-decimal notation.
This command must
be configured if GGSN's user-data mode-preference is Unicast.
Usage:
Use this command to
configure user data mode and other parameters in the BMSC profile for
user data of MBMS user service.
GGSN can receive multicast
data from BMSC in one of two modes - Multicast or Unicast. In Unicast
mode, BM-SC tunnels the multicast data to the GGSN in an IP-in-IP
tunnel instead of direct multicast. This command with the mode-preference keyword
configures the GGSN's preferred mode for receiving multicast data.
IMPORTANT:
Both GGSN and BMSC
must support the Unicast mode of multicast data transfer. If any GGSN
or BMSC does not support Multicast mode, BMSC will transfer multicast
data using Unicast mode only.
Use the unicast-self-address keyword
to configure the GGSN's IP address which the BMSC should use as
the outer destination address for the IP-in-IP tunnel to send multicast
data, if the selected user data mode to receive multicast data is Unicast.
Example:
The following command
sets the MBMS data transfer mode to unicast:
default gmb user-data
mode-preference
