Figure 3: Multicast Traffic Receipt Without Forwarding

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.
Use to activate the QoS adjust function on the router.
Example
host1(config)#ip multicast-routing bandwidth-map mcast-bandwidths
Use the no version to disable the multicast QoS adjustment function on the router.
See ip multicast-routing bandwidth-map.
You can configure IPv4 multicast to replicate packets to optimized hardware on a logical
port instead of using the forwarding controller (FC) on the router.
The bandwidth between the line module and the I/O module or IOA on the E Series router
is limited. A high-density Ethernet module provides eight physical ports that can consume
