    Cisco IOS XR Software support
    Modular software design: Cisco IOS XR Software delivers high routing scalability, availability, service isolation, and easy management for next-generation networks. Operating system infrastructure protection: Microkernel design keeps only critical functions in the kernel to prevent failures in applications, file systems, or drivers from impacting the whole system. Process and thread protection: Each process and thread runs in its own protected memory space, using secure, version-controlled APIs for inter-process communication, which limits the impact of failures. Process restart: Critical control-plane processes can be restarted individually, manually or automatically, without rebooting the full OS, helping to maintain continuous system availability. State checkpointing: Supports maintaining memory and critical operating state across process restarts so routing adjacencies and signaling state can be preserved during RSP switchover.
    Flexible Ethernet services
    Ethernet virtual connections (EVCs): Support for EVC-based Ethernet services for specific service types or end users, working with MPLS-based L2VPNs and native Ethernet switching. Flexible VLAN classification: Classify VLANs into EFPs using single-tagged VLANs, double-tagged VLANs (QinQ, 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists. IEEE bridging: Native bridging based on IEEE 802.1Q, IEEE 802.1ad, 802.1ah, and QinQ VLAN encapsulation. IEEE 802.1s Multiple Spanning Tree (MST): Extends 802.1w RSTP to multiple spanning trees for fast convergence and load balancing. MST Access Gateway: Provides resilient, fast-convergence aggregation and access to Ethernet-based access rings.
    L2VPN services
    Virtual Private LAN Services (VPLS): Connects multiple sites in a single bridged domain over a managed IP/MPLS core, presenting a simple Ethernet interface and allowing flexible bandwidth not tied to physical ports. Hierarchical VPLS (HVPLS): Adds hierarchy at the edge for higher scale, supporting QinQ access and Ethernet over MPLS (pseudowire) access. Virtual Private Wire Service (VPWS) with Ethernet over MPLS (EoMPLS): Transports Ethernet frames across an MPLS core using pseudowires per EFP or per port. Pseudowire redundancy: Allows backup pseudowire definition to protect primary pseudowires. G.8032: Sub-50-ms Ethernet ring protection, compliant with ITU-T G.8032 v2 on Cisco ASR 9000. Multisegment pseudowire stitching: Interworks two pseudowires into a cross-connect relationship.
    Multicast
    IPv4 Multicast: Supports IGMPv2/v3, PIM-SSM, PIM-SM, PIM SSM Mapping, MSDP, Multicast VPN, and Anycast RP. IGMP v2 and v3 snooping: Layer 2 snooping of IGMP joins at VLAN or pseudowire level, summarizing joins upstream so only watched channels are forwarded in broadband deployments.
    OA&M
    Ethernet OA&M (IEEE 802.3ah): Link-layer OA&M to monitor physical link health and support fault isolation; works with 802.1ag for fast link-failure detection and remote signaling. EOAM (IEEE 802.1ag): Ethernet Connectivity Fault Management (E-CFM) for discovery and verification of paths through 802.1 bridges and LANs. EOAM (ITU Y.1731): Fault Management (FM) and Performance Monitoring (PM) for verification, troubleshooting, and SLA measurement of delay, latency, and loss. Ethernet LMI (E-LMI): Protocol between CE and PE on the UNI link to report status and configuration of Ethernet services. MPLS OA&M: Supports LSP ping, LSP traceroute, and VCCV.
    Layer 3 routing
    IPv4 routing: Supports BGP, IS-IS, OSPF, RIP, static routing, IPv4 Multicast, RPL, HSRP, and VRRP. IPv6 routing: Supports OSPFv3, IS-IS, VRRPv6, DHCPv6 relay, and static IPv6 routing. BGP Prefix Independent Convergence (PIC): Enables fast convergence of BGP routes using Cisco IOS XR fast-convergence capabilities.
    MPLS L3VPN
    MPLS L3VPN: Scalable IPv4 Layer 3 VPN backbone services over MPLS for IP VPN-based value-added services, hosting, commerce, and telephony. Carrier supporting carrier (CSC): Lets an MPLS VPN provider connect remote sites over another provider’s backbone while keeping customer VPN address spaces private (per IETF RFC 4364). Selective VRF Download: Downloads VRF FIB entries only to line cards that host that VRF, increasing chassis FIB scale without loading unused entries. 6PE and 6VPE: Introduces IPv6 from the edge over IPv4/MPLS backbones, without IPv6 addressing restrictions and without impacting the stable IPv4 core.
    MPLS Traffic Engineering (TE)
    MPLS Traffic Engineering: Supports TE-FRR, RSVP, LDP, and T-LDP. MPLS Traffic Engineering Preferred Path: Maps pseudowires to specific MPLS TE tunnels, cross-connecting attachment circuits to TE tunnel interfaces instead of PE IP addresses. MPLS Traffic Engineering Auto-Bandwidth: Automatically adjusts bandwidth allocation for TE tunnels based on measured load. Point-to-Multipoint (P2MP) Traffic Engineering: Forwards MPLS traffic from one source to multiple destinations with explicit paths and extends FRR protection to P2MP sub-LSPs.
    High availability
    MPLS TE-FRR: Provides Layer 3 protection switching and temporary rerouting around failed links, nodes, or paths for MPLS LSPs. Bidirectional Forwarding Detection (BFD): Fast forwarding-path failure detection across media, encapsulations, topologies, and routing protocols. 802.3ad Link Aggregation Bundles: Bundles multiple links for resiliency and load balancing. Multichassis Link Aggregation Group (MC-LAG): Standards-based 802.3ad bundle to a pair of Cisco ASR 9000 routers that act as one device, enabling rapid restoration and supporting L2VPN, L3VPN, residential backhaul, mobile aggregation, and provider edge services.
    Manageability
    Cisco IOS XR Software manageability: Modular CLI, SNMP, CDP, LLDP, and native XML interfaces. Smart Call Home (SCH): Proactive support that detects and reports issues before they affect services, reducing troubleshooting time. Cisco Active Network Abstraction (ANA): Vendor-neutral management framework that discovers and tracks network elements in near real time, aggregating VNEs into a virtual network. Provides simplified OSS integration, a flexible common infrastructure for resource management, and consistent procedures and interfaces for all elements.
    Security
    Cisco IOS XR Software: Comprehensive security including ACLs, control-plane protection, routing authentication, AAA and TACACS+, SSH, SNMPv3, and RPL support. Layer 2 ACLs: MAC-based filtering under an EVC. Layer 3 ACLs: IPv4 packet attribute-based filtering. Additional security features: 802.1ad L2CP and BPDU filtering, MAC limiting per EFP or bridge domain, unicast/multicast/broadcast storm control, Unknown Unicast Flood Blocking (UUFB), DHCP snooping, URPF, control-plane security, Dynamic ARP Inspection (DAI), and IP Source Guard (IPSG).
