Ipv6 Dcscm Configuration Task Sequence - Planet XGS3-42000R User Manual

IP v6 DCSCM Cont rollable Multicast technology proceeds as the following way:
1. If source controlled multicast is configured on the edge switches, only the multicast data of the
specified group from the specified source can pass.
2. The RP switches which are the core of PIM-SM will directly send REGIS TE R_S TOP as response to
the REGIS TE R messages not from the specified source and specified group, and no entry is allowed to
be creat ed. (This task is implemented in the PIM-SM module).
The control of multicast users of IP v6 DCS CM technology is implemented on the basis of cont rolling the MLD
message sent from the users, so the control module is MLD snooping and the MLD module, the c ontrol logic
of which includes the following three methods: controlling according to the VLAN+MAC sending the message,
controlling according to the IP address sending the message, and controlling according to the input port of the
message. MLD snooping can adopts all the three methods at the same time, while the MLD module, at the
third layer, can only control the IP address sending the message.
The service-priority-oriented policy multicast of IP v6 DCS CM technology adopts the following met hod: for the
confined multicast data, the user-specified priority will be set at the access point, enabling the data can be
sent at a higher priority through TRUNK, and guaranteeing that the data can be sent through the whole net at
the user-specified priority.

44.5.2 IPv6 DCSCM Configuration Task Sequence

1． The source control configuration
2． The destination cont rol configuration
3． The multicast policy configuration
1． The source control configuration
The source control configuration has three steps, first is globally enabling the source c ontrol, the following is
the command of globally enabling the source control:
Global Configuration Mode
ipv6 multica st source-control (necessary)
no ipv6 multica st source-control
The next is configuring the source cont rol rules, which adopts the same met hod as configuring ACL, using
Command Explanation
Globally enable the source control, the no
operation of this command will globally
disable the source control. What should be
paid attention to is that, once globally enable
the sourc e control,
messages will be dropped by default. All the
source control configurations can only be
done after globally enabled, and only when
all the configured rules are disabled, the
source control can be disabled globally.
