Configuration Guide MLD Snooping Configuration
range ff77::1 ff77::100
range ff88::123
According to this configuration, the rule for this MLD profile is to permit the multicast
addresses from ff77::1 to ff77::100 as well as ff88::123, while other multicast
addresses are all denied.
As for Version 10.4, all products support this configuration.
Configuring MLD Filtering
Under certain circumstances, you may need to control certain port so that it can only
transmit multicast data flow within a number of specific ranges and what max groups
are allowed to join under the port.
MLD Filtering can meet this demand.
You may apply certain MLD Profile under a port. When the port receives MLD Report
message, layer 2 multicast equipment will find out whether the multicast address for
this port to join is permitted by MLD Profile.
If so, joining is permitted before later
processing.
You may also configure the max group number that are permitted to join one port.
When the max group number is exceeded, layer 2 multicast equipment will no longer
receive and process MLD report message.
To configure the MLD Filtering, run the following commands:
Ruijie(config)# interface interface-id
Enter the interface configuration mode.
Ruijie(config-if)# ipv6 mld snooping
filter profile-number
(Optional) Apply the profile to this port.
profile-number: the valid range is 1-1024.
By default, no profile is associated with a
port.
Ruijie(config-if)# ipv6 mld snooping
max-groups number
(Optional) Permit a max number of
groups to join this port dynamically.
number: the valid range is 0-1024
By default, the value is 1024.
The following example shows how to configure the MLD Filtering:
Ruijie# configure terminal
Ruijie(config)# interface fastEthernet 0/1
