Configuring An Ipv6 Multicast Group Filter; Configuring The Maximum Number Of Ipv6 Multicast Groups On An Interface - HP 4800G Series Configuration Manual

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, refer to IPv6 PIM
Configuration in the IP Multicast Volume.
As a static member of an IPv6 multicast group or an IPv6 multicast source and group, an interface
does not respond to the queries from the MLD querier, nor does it send an unsolicited MLD
membership report or a MLD done message when it joins or leaves an IPv6 multicast group or an
IPv6 source and group. In other words, the interface will not become 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 as a packet filter to limit the range of multicast groups that
the interface serves.
Follow these steps to configure an IPv6 multicast group filter:
To do...
Enter system view
Enter interface view
Configure an IPv6 multicast
group filter

Configuring the Maximum Number of IPv6 Multicast Groups on an Interface

You can configure the allowed maximum number of the IPv6 multicast groups on an interface to flexibly
control the number of IPv6 multicast groups the interface can join.
Follow these steps to configure the maximum number of IPv6 multicast groups an interface can join:
To do...
Enter system view
Enter interface view
Configure the maximum number of
IPv6 multicast groups that can be
joined on the current interface
Use the command...
system-view
interface interface-type
interface-number
mld group-policy acl6-number
[ version-number ]
Use the command...
system-view
interface interface-type
interface-number
mld group-limit limit
1-12
Remarks

—
Required
By default, no IPv6 multicast
group filter is configured on this
interface, namely hosts on the
current interface can join any
valid IPv6 multicast group..
