    Cisco IOS XR Software support
    • Modular software design: Cisco IOS XR Software demonstrates Cisco networking leadership in helping customers realize the power of their networks and the Internet. The software provides exceptional routing-system scalability, high availability, service isolation, and manageability to meet the mission-critical requirements of next-generation networks.
    • Operating system infrastructure protection: Cisco IOS XR Software provides a microkernel architecture that forces all but the most critical functions, such as memory management and thread distribution, outside of the kernel. This setup prevents failures in applications, file systems, and even device drivers from causing widespread service disruption.
    • Process and thread protection: Each process – even individual process threads – occurs in its own protected memory space, and communications between processes are accomplished through well-defined, secure, and version-controlled application programming interfaces (APIs). This setup significantly minimizes the effect that any process failure can have on other processes.
    • Process restart: The line cards offer the ability to restart critical control-plane processes both manually and automatically in response to a process failure, rather than restarting the entire OS. This feature supports the Cisco IOS XR Software goal of continuous system availability and allows for quick recovery from process or protocol failures with minimal disruption to customers or traffic.
    • State checkpointing: The line cards offer the capability to maintain a memory and critical operating state across process restarts so that routing adjacencies and signaling state can be maintained during an RSP switchover.
    Flexible Ethernet services
    • Ethernet virtual connections (EVCs): Ethernet services are supported using individual EVCs to carry traffic belonging to a specific service type or end user through the network. EVC-based services can be used with MPLS-based L2VPNs and native Ethernet switching deployments.
    • Flexible VLAN classification: VLAN classification into EFPs includes single-tagged VLANs, double-tagged VLANs (QinQ and IEEE 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists.
    • IEEE bridging: The line cards support native bridging based on IEEE 802.1Q, IEEE 802.1ad, IEEE 802.1ah, and QinQ VLAN encapsulation mechanisms.
    • IEEE 802.1s Multiple Spanning Tree (MST): MST extends the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) to multiple spanning trees, providing rapid convergence and load balancing.
    • MST Access Gateway: The MST Access Gateway provides a resilient, fast-convergence mechanism for aggregating and connecting to Ethernet-based access rings.
    L2VPN services
    • Virtual Private LAN Services (VPLS): VPLS supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network. VPLS presents an Ethernet interface to customers, simplifies the LAN and WAN boundary, and supports rapid and flexible service provisioning because the service bandwidth is not tied to the physical interface. All services in a VPLS appear to be on the same LAN, regardless of location.
    • Hierarchical VPLS (HVPLS): HVPLS provides a level of hierarchy at the edge of the VPLS network for increased scale. Two options of HVPLS are supported: QinQ access and Ethernet over MPLS (pseudowire) access.
    • Virtual Private Wire Service (VPWS) with Ethernet over MPLS (EoMPLS): EoMPLS transports Ethernet frames across an MPLS core using pseudowires. Individual EFPs or traffic from an entire port can be transported over the MPLS backbone using pseudowires to an egress interface or subinterface.
    • Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire that fails.
    • G.8032: Provides sub-50-ms protection for Ethernet traffic in a ring topology. The implementation on the Cisco ASR 9000 Series is compliant with ITU-T G.8032 version 2.
    • Multisegment pseudowire stitching: A method for interworking two pseudowires together to form a cross-connect relationship.
    Multicast
    • IPv4 Multicast: Supports IGMPv2 and IGMPv3, PIM-SSM, PIM sparse mode (PIM-SM), PIM SSM Mapping, MSDP, Multicast VPN, and Anycast RP.
    • IGMPv2 and IGMPv3 snooping: Layer 2 mechanism that tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level or pseudowire level and summarized into a single upstream join. In residential broadband deployments, this allows the network to send only channels that are being watched to downstream users.
    OA&M
    • Ethernet OA&M (EOAM) (IEEE 802.3ah): Ethernet link layer OA&M provides physical-link OA&M to monitor link health and assist in fault isolation. With IEEE 802.1ag, Ethernet link layer OA&M assists in rapid link-failure detection and signaling to remote end nodes of a local failure.
    • EOAM (IEEE 802.1ag): Ethernet Connectivity Fault Management (E-CFM) provides protocols and procedures to discover and verify the path through IEEE 802.1 bridges and LANs.
    • EOAM (ITU-T Y.1731): Y.1731 provides Fault Management (FM) and Performance Monitoring (PM). FM builds on IEEE 802.1ag message types to verify the Ethernet network and troubleshoot faults. PM allows service providers to offer SLAs by measuring delay, latency, and loss across an Ethernet network.
    • Ethernet LMI (E-LMI): Protocol between the customer-edge (CE) device and provider-edge (PE) device on the PE-to-CE UNI link. It notifies the CE device of connectivity status and configuration parameters of Ethernet services available on the CE port.
    • MPLS OA&M: Supports LSP ping, LSP traceroute, and VCCV.
    Layer 3 routing
    • IPv4 routing: Supports IPv4 services and routing protocols including BGP, IS-IS, OSPF, RIP, static routing, IPv4 Multicast, RPL, HSRP, and VRRP.
    • IPv6 routing: Supports IPv6 services including OSPFv3, IS-IS, VRRPv6, DHCPv6 relay, and static routing.
    • BGP PIC: BGP Prefix Independent Convergence provides fast convergence of BGP routes using Cisco IOS XR Software innovations.
    MPLS L3VPN
    • MPLS L3VPN: IP VPN for MPLS allows deployment of scalable IPv4 Layer 3 VPN backbone services for applications, data hosting, e-commerce, and telephony services to business customers.
    • Carrier supporting carrier (CSC): Allows an MPLS VPN service provider to connect geographically isolated sites using another backbone service provider while maintaining a private address space for customer VPNs, as defined by IETF RFC 4364.
    • Selective VRF Download: Selectively downloads VRF FIB entries only to line cards with VRF membership, providing larger FIB scale at chassis level without unnecessary entries on each line card.
    • 6PE and 6VPE: Introduce IPv6 from the edge over an IPv4/MPLS backbone without IPv6 addressing restrictions and without impacting a well-controlled IPv4 backbone.
    MPLS Traffic Engineering (TE)
    • MPLS Traffic Engineering: Supports TE-FRR, RSVP, LDP, and T-LDP.
    • MPLS TE Preferred Path: Preferred tunnel path functions map pseudowires to specific TE tunnels. Attachment circuits are cross-connected to specific MPLS TE tunnel interfaces instead of remote PE router IP addresses.
    • MPLS TE Auto-Bandwidth: Automatically adjusts bandwidth allocation for TE tunnels based on measured traffic load.
    • Point-to-Multipoint (P2MP) TE: Forwards MPLS traffic from one source to multiple destinations, provides a single point of traffic control, explicit path configuration, and extends FRR protection to P2MP TE sub-LSPs.
    High availability
    • MPLS TE-FRR: Provides Layer 3 protection switching for MPLS LSPs, with temporary rerouting around a failed link, node, or path.
    • Bidirectional Forwarding Detection (BFD): Fast forwarding-path failure detection for all media types, encapsulations, topologies, and routing protocols.
    • IEEE 802.3ad Link Aggregation Bundles: Supports bundles of multiple links for resiliency and load balancing across member links.
    • Multichassis Link Aggregation Group (MC-LAG): Provides a standards-based IEEE 802.3ad bundle to connect to a pair of Cisco ASR 9000 Series routers that appear as a single router. Supports rapid restoration on link or node failure and works with L2VPN, L3VPN, residential backhaul, mobile aggregation, and service provider edge solutions.
    Manageability
    • Cisco IOS XR Software manageability: Provides modular CLI, SNMP, Cisco Discovery Protocol (CDP), LLDP, and native XML interfaces.
    • Smart Call Home (SCH): Proactive support that identifies and reports problems before they affect business operations, reducing troubleshooting time and speeding issue resolution.
    • Cisco Active Network Abstraction (ANA): Vendor-neutral management framework for multitechnology, multiservice networks. Operates between the network and OSS layer, aggregating virtual network elements into a software-based virtual network, dynamically discovering components and tracking network element status in near real time. Offers simplified OSS integration, a flexible common infrastructure for resource management, and consistent procedures and interfaces for all network elements.
    Security
    • Cisco IOS XR Software: Provides ACLs, control-plane protection, routing authentication, AAA and TACACS+, SSH, SNMPv3, and RPL support.
    • Layer 2 ACLs: Packet filtering under an EVC based on MAC addresses.
    • Layer 3 ACLs: ACL matching by IPv4 packet attributes.
    • Additional security features: 802.1ad L2CP and BPDU filtering; MAC limiting per EFP or bridge domain; unicast, multicast, and broadcast storm control on any interface or port; Unknown Unicast Flood Blocking (UUFB); DHCP snooping; Unicast Reverse Path Forwarding (URPF); control-plane security; Dynamic ARP Inspection (DAI); IP Source Guard (IPSG).
