Cisco IOS XR Software Support

Modular software design: Cisco IOS XR Software helps customers realize the power of their networks and the Internet. It offers routing-system scalability, high availability, service isolation, and manageability for mission-critical next-generation networks. Operating system infrastructure protection: Microkernel architecture moves all but the most critical functions such as memory management and thread distribution outside of the kernel to prevent failures in applications, file systems, and device drivers from causing widespread disruption. Process and thread protection: Each process and process thread runs in its own protected memory space, with communication through secure, version-controlled APIs, minimizing the impact of any process failure. Process restart: Critical control-plane processes can be restarted manually or automatically without restarting the entire OS, supporting continuous system availability and fast recovery. State checkpointing: Maintains memory and critical operating state across process restarts so that routing adjacencies and signaling state are preserved during RSP switchover.

Flexible Ethernet Services

Ethernet virtual connections (EVCs): EVCs carry traffic for specific service types or end users and can be used with MPLS L2VPNs and native Ethernet switching. Flexible VLAN classification: Single-tagged VLANs, double-tagged VLANs (QinQ and 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists mapped into EFPs. IEEE bridging: Native bridging for IEEE 802.1Q, IEEE 802.1ad, IEEE 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 connectivity 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 network, presents an Ethernet interface, and decouples service bandwidth from the physical interface. Hierarchical VPLS (HVPLS): Adds hierarchy at the VPLS edge for scale, supporting QinQ access and Ethernet over MPLS (pseudowire) access. Virtual Private Wire Service (VPWS) with EoMPLS: Transports Ethernet frames across an MPLS core using pseudowires for individual EFPs or entire ports. Pseudowire redundancy: Allows backup pseudowires to protect primary pseudowires. G.8032: Sub-50 ms protection for Ethernet traffic in ring topologies, compliant with ITU-T G.8032 v2 on Cisco ASR 9000 Series. Multisegment pseudowire stitching: Interworks two pseudowires to form a cross-connect.

Multicast

IPv4 Multicast: Supports IGMPv2, IGMPv3, PIM-SSM, PIM-SM, PIM SSM Mapping, MSDP, Multicast VPN, and Anycast RP. IGMP v2 and v3 snooping: Layer 2 mechanism to track multicast membership at VLAN or pseudowire level, summarizing joins upstream and sending only watched channels downstream, ideal for residential broadband IPTV deployments.

OA&M

Ethernet OAM (IEEE 802.3ah): Provides physical-link OAM to monitor link health and assist in fault isolation and rapid link-failure detection. EOAM (IEEE 802.1ag): Ethernet Connectivity Fault Management (E-CFM) for discovery and verification of paths through 802.1 bridges and LANs. EOAM (ITU-T Y.1731): Fault Management builds on 802.1ag for fault verification and troubleshooting; Performance Monitoring measures delay, latency, and loss to support Ethernet SLAs. Ethernet LMI (E-LMI): Protocol between CE and PE on the UNI link to notify CE of connectivity status and Ethernet service configuration. MPLS OAM: Supports LSP ping, LSP traceroute, and VCCV.

Layer 3 Routing

IPv4 routing: Supports BGP, IS-IS, OSPF, RIP, static routes, IPv4 Multicast, Routing Policy Language (RPL), HSRP, and VRRP. IPv6 routing: Supports OSPFv3, IS-IS, VRRPv6, DHCPv6 relay, and static routing. BGP Prefix Independent Convergence (PIC): Enables fast convergence of BGP routes using IOS XR convergence mechanisms.

MPLS L3VPN

MPLS L3VPN: Provides scalable IPv4 Layer 3 VPN backbone services for value-added services such as applications, hosting, e-commerce, and telephony. Carrier Supporting Carrier (CSC): Allows an MPLS VPN provider to interconnect isolated sites over another provider’s backbone while keeping private VPN address spaces, as per IETF RFC 4364. Selective VRF Download: Downloads VRF FIB entries only to line cards with VRF membership, increasing chassis FIB scale and avoiding unnecessary entries. 6PE and 6VPE: Introduces IPv6 from the edge over an IPv4/MPLS backbone without IPv6 addressing restrictions or impact on the existing IPv4 core.

MPLS Traffic Engineering (TE)

MPLS TE: Supports TE-FRR, RSVP, LDP, and T-LDP. MPLS TE Preferred Path: Maps pseudowires to specific TE tunnels, cross-connecting attachment circuits to MPLS TE tunnel interfaces instead of remote PE IP addresses. MPLS TE Auto-Bandwidth: Automatically adjusts tunnel bandwidth based on measured traffic load. Point-to-Multipoint (P2MP) TE: Forwards MPLS traffic from one source to multiple destinations with a single point of control, explicit paths for optimized distribution, and FRR protection for 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 for all media, encapsulations, topologies, and routing protocols. 802.3ad Link Aggregation Bundles: Multiple links bundled for resiliency and load balancing. Multichassis Link Aggregation Group (MC-LAG): 802.3ad bundle across a pair of Cisco ASR 9000 routers appearing as a single router to the attached device, enabling rapid restoration for business L2VPN, L3VPN, residential backhaul, mobile aggregation, and service provider edge.

Manageability

Cisco IOS XR manageability: Provides CLI, SNMP, CDP, LLDP, and native XML interfaces. Smart Call Home (SCH): Proactive support that identifies and reports problems before they affect services for faster troubleshooting. Cisco Active Network Abstraction (ANA): Vendor-neutral management framework that discovers network components, tracks status in near real time, and aggregates VNEs into a virtual network, simplifying OSS integration, providing a common management infrastructure, and consistent procedures and interfaces for all network elements.

Security

Cisco IOS XR security: Access control lists (ACLs), control-plane protection, routing authentication, AAA and TACACS+, SSH, SNMPv3, and RPL-based policy control. Layer 2 ACLs: Filters packets under an EVC based on MAC addresses. Layer 3 ACLs: Matches IPv4 packets on Layer 3 attributes. Additional security: 802.1ad L2CP and BPDU filtering, MAC limiting per EFP or bridge domain, unicast/multicast/broadcast storm control on any port, Unknown Unicast Flood Blocking (UUFB), DHCP snooping, URPF, control-plane security, Dynamic ARP Inspection (DAI), and IP Source Guard (IPSG).
