How to Configure IPv6 Support on the Cisco ASR 901 Router
QoS for IPv6
The Cisco ASR 901 router support of QoS features for IPv6 environments include ingress packet
classification, policing, marking on Ethernet interfaces. It also supports egress packet classification,
marking, scheduling, per interface and per qos-group shaping, Low Latency Queuing (LLQ), and
weighted random early detection (WRED) on GigabitEthernet interfaces.
Note Queuing, shaping, scheduling and LLQ is not supported on the ingress path for the Ethernet interfaces.
Policing is not supported on the egress path for GigabitEthernet interfaces.
The QoS implementation for IPv6 environment in the Cisco ASR router is the same as that of IPv4. For

Configuring IPv6 Addressing and Enabling IPv6 Routing
Perform this task to assign IPv6 addresses to individual router interfaces and enable IPv6 traffic
forwarding globally on the router. By default, IPv6 addresses are not configured, and IPv6 routing is
disabled.
