The following sections describe the features supported on the Cisco ASR 9000 Series Router platform:

The Cisco ASR 9000 Series Router platform is not supported on Cisco IOS XR Software Release 3.8.0.

The following features introduced in Cisco IOS XR Software Release 3.9.2 are supported on the 
Cisco ASR 9000 Series Router platform:

Cisco IOS XR Software Release 3.9.2 introduces support on the Cisco ASR 9000 Series Router 
platform for packet forwarding and routing according to customer defined policies. 

An access control list (ACL) consists of one or more access control entries (ACE) that collectively 
define the network traffic profile. This profile can then be referenced by Cisco IOS XR software 
features such as traffic filtering, route filtering, QoS classification, and access control. Each ACL 
includes an action element (permit or deny) and a filter element based on criteria such as source 
address, destination address, protocol, and protocol-specific parameters. 

Prefix lists are used in route maps and route filtering operations and can be used as an alternative to 
access lists in many Border Gateway Protocol (BGP) route filtering commands. A prefix is a portion 
of an IP address, starting from the far left bit of the far left octet. By specifying exactly how many 
bits of an address belong to a prefix, you can then use prefixes to aggregate addresses and perform 
a function on them, such as redistribution (filter routing updates). 

Support for ABF is only for IPv4 and Ethernet line cards. IPv6 and other interfaces are not 
supported

ABF is an ingress line card feature and the egress line card must be ABF aware.
