NOTE:

Ensure that PIM-SM (or any other upstream multicast protocol) is informed

of the group (or source-group) interest.

Activating Multicast QoS Adjustment Functions

The

ip 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 “Defining a Multicast Bandwidth Map” on page 10 for details.

ip multicast-routing bandwidth-map

■

Use to activate the QoS adjust function on the router.

■

Example

host1(config)#

ip multicast-routing bandwidth-map mcast-bandwidths

■

Use the

version to disable the multicast QoS adjustment function on the

router.

■

See ip multicast-routing bandwidth-map.
