ipv6 multicast-routing bandwidth-map
• Use to enable the QoS adjust function on the router.
• Example
host1(config)#ipv6 multicast-routing bandwidth-map mcast-bandwidths
• Use the no version to disable the multicast QoS adjustment function on the router.
• See ipv6 multicast-routing bandwidth-map.
Configuring Hardware Multicast Packet Replication
You can configure IPv6 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
the bandwidth between the line module and the I/O module or IOA before providing
enough traffic to support egress line rate for all of these ports.
Figure 17 on page 155 displays how multicast traffic is typically replicated on the line
module. Each of these replicated packets is transmitted from the line module to the I/O
module or IOA.
