3． The configuration of multicast policy
The multicast policy adopts the method of specifying a priority for the specified multicast data to meet the
user’s particular demand, what should be paid attention to is that only when multicast data is transmitted in
TRUNK, can it be taken special care of. The configuration is quite simple, for only one command is needed,
that is set priority for the specified multicast, the following is the command:
Command Explanation
Global Configuration Mode
[no] ipv6 multicast policy <IPADDRESS/M>
<IPADDRESS/M> cos <priority>
Configure multicast policy, set priority
for sources and groups in a specified
range, the priority valid range is 0 to 7.
49.5.3 IPv6 DCSCM Typical Examples
1． Source control
In order to prevent an edge switch sends multicast data at will, we configure on the edge switch that only the
switch whose port is Ethernet1/0/5 can send multicast data, and the group of data should be ff1e::1. The
uplink port Ethernet1/0/25 can forward multicast data without being restricted, so we can configure as follows.
Switch(config)#ipv6 access-list 8000 permit any-source ff1e::1
Switch(config)#ipv6 access-list 8001 permit any any
Switch(config)#ipv6 multicast source-control
Switch(config)#interface Ethernet1/0/5
Switch(Config-If-Ethernet1/0/5)#ipv6 multicast source-control access-group 8000
Switch(config)#interface Ethernet1/0/25
Switch(Config-If-Ethernet1/0/25)#ipv6 multicast source-control access-group 8001
2． Destination control
We want to confine that the users of the segment whose address is fe80::203:fff:fe01:228a/64 can not join the
ff1e::1/64 group, so we can configure as follows:
First, enable MLD Snooping in the VLAN where it locates (in this example, it is VLAN2).
Switch(config)#ipv6 mld snooping
Switch(config)#ipv6 mld snooping vlan 2
Then configure relative destination control access list and configure specified IPv6 address to use this access
list.
Switch(config)#ipv6 access-list 9000 deny any ff1e::1/64
Switch(config)#ipv6 access-list 9000 permit any any
Switch(config)#multicast destination-control
