# Activating IPv6 Multicast QoS Adjustment Functions

The ipv6 multicast-routing bandwidth-map command activates the specified bandwidth map. By activating the bandwidth map, this command also activates the multicast QoS adjustment function contained in the bandwidth map.

| Caution: To activate multicast QoS adjustment, you must first create a bandwidth map. See Example: Configuring an IPv6 Multicast Bandwidth Map for details.

To enable the QoS adjust function on the router with the configured route map:

- Issue the ipv6 multicast-routing bandwidth-map command in Global Configuration mode.
  host1(config)#ipv6 multicast-routing bandwidth-map mcast-bandwidths

Use the no version to disable the multicast QoS adjustment function on the router.
