Configuring an ipv6 multicast group filter – H3C Technologies H3C SecPath F1000-E User Manual

NOTE:
•
Before you can configure an interface of an IPv6 PIM-SM device as a static member of an IPv6 multicast
group or an IPv6 multicast source and group, if the interface is IPv6 PIM-SM enabled, it must be an IPv6
PIM-SM DR. If this interface is MLD enabled but not IPv6 PIM-SM enabled, it must be an MLD querier.
For more information about IPv6 PIM-SM and a DR, see "Configuring IPv6 PIM."
•
A static member port does not respond to queries from the MLD querier. When you configure an
interface as a static member port or remove this configuration on the interface, the interface does not
unsolicitedly send any MLD report or an MLD done message. In other words, the interface is not a real
member of the IPv6 multicast group or the IPv6 multicast and source group.
Configuring an IPv6 multicast group filter
To restrict the hosts on the network attached to an interface from joining certain IPv6 multicast groups,
you can set an IPv6 ACL rule on the interface so that the interface maintains only the IPv6 multicast
groups matching the criteria.
To configure an IPv6 multicast group filter:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter interface view.
interface interface-type
interface-number
N/A
3.
Configure an IPv6 multicast
group filter.
mld group-policy acl6-number
[ version-number ]
By default, no IPv6 group filter is
configured on the interface. That is,
hosts on the current interface can
join any valid multicast group.
Setting the maximum number of IPv6 multicast groups that an
interface can join
Step Command
Remarks
1.
Enter system view.

2.
Enter interface view.
interface interface-type
interface-number
N/A
3.
Configure the maximum number of
IPv6 multicast groups that the
interface can join.
mld group-limit limit
By default, the upper limit is
4096.
NOTE:
This configuration takes effect for dynamically joined IPv6 multicast groups but not the statically
configured multicast groups.
