The configuration of destination control
The configuration of destination control is similar to that of source control, and also
has three steps:
First, globally enable the destination control, since destination control needs to avoid
the unauthorized users from receiving multicast data, once it is enabled globally, the
switch will stop broadcasting received multicast data, so if a switch has enabled
destination control, users should not connect two or more other Layer three switches
within the same VLAN where it locates. The following is the configuration command:
Command
Explanation
Global Configuration Mode
multicast destination-control(necessary)
Globally enable IPV4 and IPv6
destination control, the no operation
of this command will globally disable
destination control. All of the other
configuration can only take effect
after globally enabled.
The next is configuring destination control rules, which are similar to that of source
control, but using ACL number from 9000 to 10099 instead.

Used
to
configure
destination
control rules, these rules can only
take effect when applied to specified
source IP, VLAN-MAC or port. The
no operation of this rule will delete
the specified rule.
The last step is to configure the rules to the specified source IP, source VLAN MAC or
the specified port. What should be paid attention to is that only when the
MLD-SNOOPING is enabled, these rules can be globally used, or, only rules of source IP
can be used in MLD protocol. The following is the configuration command:
