(Optional) Configuring the Range of Multicast Groups That an Interface Can Join

(Optional) Configuring the Range of Multicast Groups That an Interface Can Join

Context

To limit the range of IPv6 multicast groups that an interface can join, configure ACL6 rules to filter received Multicast Listener Report messages so that the interface maintains multicast membership only in the allowed multicast groups.

Before specifying the range of multicast groups that an interface can join, configure an IPv6 access control list (ACL6) to define the range of multicast groups. For details about the ACL6 configuration, see "ACL Configuration" in the Huawei AR Series Access Routers Configuration Guide - Security.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The interface view is displayed.

  3. Run:

    mld group-policy { acl6-number | acl6-name acl6-name } [ 1 | 2 ]

    The range of multicast groups that the interface can join is configured.

    By default, an interface can join any multicast group.

    NOTE:

    When configuring an ACL6 rule for an interface, use the permit parameter in the rule command to allow hosts connected to the interface to join groups within the specified range. If no rule is configured in the ACL6, hosts connected to the interface cannot join any multicast groups.
