Applying a Basic ACL6

Basic ACL6s can be used in device management, QoS services, multicast packet filtering, and routing policies.

Context

Table 1 describes the typical applications of basic ACL6s.

**Table 1** Typical applications of basic ACL6s
Typical Application	Usage Scenario	Operation
Device management	When a device functions as a TFTP server, configure a basic ACL6 to allow only the clients that match specific ACL6 rules to access the server.	For details on how to configure rights to access a TFTP server, see Configuring TFTP Access Authority.
Multicast packet filtering	To filter multicast packets, you can configure a basic ACL6 to receive or forward only the multicast packets that match the ACL6 rules.	For details on how to filter multicast packets, see Setting a Multicast Source Address Range Setting a Legal C-RP Address Range Setting a Legal BSR Address Range Setting an SSM Group Address Range
Routing policies	To control the reception and advertisement of routing information on a device, configure a basic ACL6 on the device to allow the device to receive or advertise only the routes that match the ACL6 rules.	For details on how to control the reception and advertisement of routing information on a device, see Configuring OSPFv3 to Filter Received Routes Configuring OSPFv3 to Filter the Routes to Be Advertised Filtering IPv6 IS-IS Routes Configuring IPv6 IS-IS to Import External Routes Configuring a Policy for Receiving BGP4+ Routes Configuring a Policy for Advertising BGP4+ Routes
QoS services	To process different types of traffic, configure a basic ACL6 to perform traffic policing, traffic shaping, or traffic classification on traffic that matches the ACL6 rules.	For details on how to process different types of traffic, see Configuring the Traffic Policing Policy, Configuring Traffic Shaping, and Configuring Traffic Behaviors.
