(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 NetEngine AR Configuration Guide - Security.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- 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.
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.
