The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The bandwidth-based call admission control (CAC) for IPv6 multicast feature implements a way to count per-interface mroute state limiters using cost multipliers. This feature can be used to provide bandwidth-based CAC on a per-interface basis in network environments where the multicast flows use different amounts of bandwidth.
This feature limits and accounts for IPv6 multicast state in detail. When this feature is configured, interfaces can be limited to the number of times they may be used as incoming or outgoing interfaces in the IPv6 multicast PIM topology.
With this feature, device administrators can configure global limit cost commands for state matching access lists and specify which cost multiplier to use when accounting such state against the interface limits. This feature provides the required flexibility to implement bandwidth-based local CAC policy by tuning appropriate cost multipliers for different bandwidth requirements.
Device administrators can configure global limit cost commands for state matching access lists.
In bandwidth-based CAC for IPv6, device administrators can configure global limit cost commands for state matching access lists. Perform this task to configure an access list to configure a state matching access list.

Bandwidth-based CAC for IPv6 counts per-interface IPv6 mroute states using cost multipliers. With this feature, device administrators can specify which cost multiplier to use when accounting such state against the interface limits.
The following example configures the global limit on the source device.
ipv6 multicast limit cost cost-list 2
The following example shows how to configure an access list to use for bandwidth-based CAC:
ipv6 access-list cost-list permit any ff03::1/64
The following example configures the interface limit on the source device's outgoing interface Ethernet 1/3.
interface Ethernet1/3 ipv6 address FE80::40:1:3 link-local ipv6 address 2001:DB8:1:1:3/64 ipv6 multicast limit out acl1 10
