Introduction to the Cisco ASR 9000 Series Aggregation Services Router
Cisco ASR 9000 Series Router Overview
• Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Configuration
GuideLawful Intercept IPv4—Lawful intercept is the process by which law enforcement agencies
conduct electronic surveillance of circuit-mode and packet-mode communications, authorized by
either a judicial order or an administrative order. Service providers worldwide are legally required
to assist law enforcement agencies in conducting electronic surveillance in both circuit-switched
and packet-mode networks. For more information on Lawful Intercept IPv4, see the Cisco ASR 9000
Series Aggregation Services Router System Security Configuration Guide.
• Ethernet-Local Management Interface (E-LMI)—E-LMI is an asymmetric protocol that runs on the
PE-to-CE link or the User-Network Interface (UNI). The user-facing Provider Edge (uPE) device
uses E-LMI to communicate the connectivity status (EVC status) and configuration parameters of
the Ethernet services available on the UNI of the CE device. For more information on configuring
E-LMI, see the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware
Component Configuration Guide.
• Multigigabit Service Control Platform (MGSCP)—The MGSCP solution uses EtherChannel (EC)
and the Link Aggregation Control Protocol (LACP) 802.3ad to enable the task of scaling the SCE
platform by sending the traffic to an EC. EC load balancing is used to distribute the traffic over
several SCE platforms. For more information on MGSCP, see the Cisco ASR 9000 Series
Aggregation Services Router Interface and Hardware Component Configuration Guide.
• Integrated Routing and Bridging (IRB) Interoperability Support on ASR 9000 SIP-700—This
feature provides IRB interoperability support between SIP-700 and Ethernet line cards. For more
information on IRB interoperability support, see the Cisco ASR 9000 Series Aggregation Services
Router Interface and Hardware Component Configuration Guide.
• IPv6 Access Services: Dynamic Host Configuration Protocol (DHCP) Relay Agent—RFC 3315
defines the DHCP relay agent that resides on a client's link and relays messages between the client
and the server. This agent allows a DHCP client to send a message to a DHCP server that is not
connected to the same link. For more information on the DHCP Relay Agent, see the Cisco ASR
9000 Series Aggregation Services Router IP Addresses and Services Configuration Guide.
• Integrated Service Module (ISM)—This feature is used for video integration and other services,
such as content streaming on the ASR9000-SIM-100 platform. For more information on installing
the ISM line cards, see the Cisco ASR 9000 Series Aggregation Services Router ISM Line Card
Installation Guide.
• IEEE 802.1ab Link Layer Discovery Protocol (LLDP)—This feature enables the task of discovering
the network topology in a standardized way using standard management tools, such as SNMP. The
LLDP is initially deployed in Ethernet-based enterprise switching networks, which can also be used
over other media types, such as Token Ring and FDDI. For more information on configuring LLDP,
see the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component
Configuration Guide.
• High Availability for Lawful Intercept—This feature provides operational continuity of the TAP
flows and provisioned MD tables to reduce loss of information due to route processor fail over
(RPFO). For more information on high availability for lawful intercept, see the Cisco ASR 9000
Series Aggregation Services Router System Security Configuration Guide.
• Bidirectional Forwarding (BFD) on Multiple Hops—This feature provides sub-second forwarding
failure detection for a destination more than one hop, and up to 255 hops, away. BFD multihop is
supported on all currently supported media-type for BFD singlehop. For more information on how
to configure BFD sessions, see the Cisco ASR 9000 Series Aggregation Services Router Interface
and Hardware Component Configuration Guide.
