Introduction

Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and high performance.

Cisco IOS XR software running on the Cisco ASR 9000 Series Router provides the following features and benefits:

•IP and Routing—Supports a wide range of IPv4 and IPv6 services and routing protocols; such as Border Gateway Protocol (BGP), Routing Information Protocol (RIPv2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol features (VRRP).

•Ethernet Services—The Cisco IOS XR software Release 3.7.2 running on the Cisco ASR 9000 Series Router supports the following Ethernet features:

–Ethernet Virtual Connections (EVCs)

–Flexible VLAN classification

–Flexible VLAN translation

–IEEE bridging

–IEEE 802.1s Multiple Spanning Tree (MST)

–MST Access Gateway

–L2VPN

–Virtual Private LAN Services (VPLS), Hierarchical VPLS (H-VPLS), Virtual Private Wire Service (VPWS), Ethernet over MPLS (EoMPLS), pseudowire redundancy, and multi segment pseudowire stitching

•BGP Prefix Independent Convergence—Provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or with out MPLS. This fast convergence innovation is unique to Cisco IOS XR software.

•Multiprotocol Label Switching (MPLS)—Supports MPLS protocols, including Traffic Engineering (TE) [including TE-FRR and TE Preferred Path], Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Targeted LDP (T-LDP), Resource Reservation Protocol (RSVP), Differentiated Services (DiffServ)-aware traffic engineering, and Layer 3 Virtual Private Network (L3VPN).

•Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only. The Cisco ASR 9000 Series Router also supports Bidirectional Protocol Independent Multicast (BIDIR-PIM), Automatic route processing (AutoRP), Multiprotocol BGP (MBGP), Multicast Source Discovery Protocol (MSDP), Internet Group Management Protocol Versions 2 and 3 (IGMPv2 and v3), and IGMPv2 and v3 snooping.

•Quality of Service (QoS)—Supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR supports modular QoS command-line interface (MQC). MQC is used to configure various QoS features on various Cisco platforms, including the Cisco ASR 9000 Series Router. Supports the following:

–Class-Based Weighted Fair Queuing (CBWFQ)

–Weighted Random Early Detection (WRED)

–Priority Queuing with propagation

–2-rate 3-color (2R3C) Policing

–Modular QoS CLI (MQC)

–4-level Hierarchical-QoS

•DAGR—Direct-Attached Gateway Redundancy (DAGR) is a feature within the ARP process that serves as an alternative solution to Integrated Routing and Bridging (IRB).

•VRF-Lite— VRF (VPN routing and forwarding)-lite support allows a router using VRF-lite to segment its LAN traffic by placing each client or organization with its own IP address space either on separate Ethernet interfaces or through one Ethernet interface segmented into multiple sub-interfaces.

•BFD over VRF—Supports running Bidirectional Forwarding Detection (BFD) over a VRF (VPN routing and forwarding) instance.

•Manageability—Provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. Includes a comprehensive set of Syslog messaging.

•Security—Provides comprehensive network security features including Layer 2 and Layer 3access control lists (ACLs); routing authentications; Authentication, Authorization, and Accounting (AAA)/Terminal Access Controller Access Control System (TACACS+); Secure Shell (SSH); Management Plane Protection (MPP) for control plan security; and Simple Network Management Protocol version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).

•Availability—Supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, nonstop routing for ISIS, LDP and OSPF, and nonstop forwarding (NSF).

•Enhanced core competencies:

–IP fast convergence with Fast Reroute (FRR) support for Intermediate System-to-Intermediate System (IS-IS)

–Traffic engineering support for unequal load balancing

–Path Computation Element (PCE) capability for traffic engineering

Important Notes

For Cisco IOS XR Software Release 3.7.2, the Cisco ASR 9000 Series Router does not support the following inventory schemas:

–vkg_invmgr_adminoper.xsd

–vkg_invmgr_common.xsd

–vkg_invmgr_oper.xsd

•Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.

•Card, fan controller, and RSP removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RSP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco ASR 9000 Series Router Getting Started Guide for procedures.

•Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration maximum for your purpose.

•Installing a Line Card—For a fully populated 40-port high density Line Card with cable optics, maintenance time required for card replacement is higher. For more information about Line Card installation and removal, refer to the Cisco ASR 9000 Aggregation Services Router Ethernet Line Card Installation Guide.

Caveats

Caveats describe unexpected behavior in Cisco IOS XR software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.

This section lists the caveats for Cisco ASR 9000 Series Router Software Release 3.7.2 and the Cisco ASR 9000 Series platform.

Cisco IOS XR Software Caveats

The following caveats apply to Release 3.7.2 of the Cisco IOS XR software:

•CSCsy24646

Basic Description:

ipv4_mfwd_partner[171]: %ROUTING-IPV4_MFWD-5-MRIB_UPDATE_RETRY seen

Symptom:

The following error messages are printed to console:

LC/0/6/CPU0:Mar 5 14:40:03.839 : ipv4_mfwd_partner[177]: %ROUTING-IPV4_MFWD-5-MRIB_UPDATE_RETRY : One or more route update not fully processed. Re-downloading...

LC/0/1/CPU0:Mar 6 10:44:37.919 : ipv4_mfwd_partner[173]: %ROUTING-IPV4_MFWD-4-FROM_MRIB_UPDATE : MFIB couldn't process update from MRIB : Unable to create interface Nf0x02003F00 to process route update (0xe0000000):(22.22.1.1,224.0.1.40/64)attr: 0x0, mdf_attr: 0x703e - No such file or directory

These error messages are usually seen after reloading a line card. In addition to seeing these error messages, the PIM adjacencies between the PE routers does not come up.

Conditions:

This issue is seen on a Cisco Internet Series c12416 router booted with Cisco IOSXR version 3.6.3-14i. The router contains redundant PRP-2 processors and the chassis is fully loaded with E5 and E3 line cards.

Workaround:

none

•CSCsw50291

Failed to purge NULL route after deleting summary-prefix

Symptom:

This happens when SUMMARIZATION is configured on the router. In particular, this can happen only when same summarization exists on more than one router. We may populate wrong state in cef TABLE that can cause the traffic drop

Conditions:

Under different preference of same routes exists then we can potentially hit this issue

Workaround:

One way to fix this issue to avoid the summarization or fix the multiple sources contributing the same prefix.

Caveats Specific to the Cisco ASR 9000 Series Router

The following caveats are specific to the Cisco ASR 9000 Series platform:

•CSCsv61389

Basic Description:

VRRP & FRR protection may exhibit temporary traffic loss during line card power cycle.

Symptoms:

VRRP & FRR traffic failover time in excess of 1 second, up to approximately 2.2 seconds.

Conditions:

Failovers prompted by the "hw-module loc <> reload" CLI command

Workaround:

The traffic outage is specific to CLI power cycle of the line card. Traffic switches prompted by line failure or port shutdown are not affected. In order to perform a powerlessly of the line card without the long failover time, perform a port shutdown prior to initiating the CLI command.

•CSCsx95233

Basic Description:

The interacting components when dealing with OIR in a fast OIR (< 5 seconds) can incur a race condition such that one of the race condition cases cause LC long timeout and recovery boot time.

Symptoms:

In this race condition case, LC takes approximately 10 minutes to recover and boot.

Condition:

Race condition outcome where the LC is re-inserted quickly such that 1) offline is slow and therefore not reported to shelfmgr; and 2) post-notify not reported during OIR events; these two events cause long FSM timing, timeout, and subsequent restart of the card, hence long boot time.

Workaround:

LC OIR time to be > 5 seconds, such that the offline from the (R)emoval event followed by the (I)nsertion event are serially reported.

•CSCsx57294

Basic Description:

Over subscribed traffic drops are not shown in bundle interface egress drop count

Symptom:

Drop counts for member links of a bundle interface are not accumulated in the bundle interface counters.

Conditions:

If a bundle member link is oversubscribed, drop counts will be accumulated in that member link, but the bundle interface will not show the aggregate drop counts from any of its members.

Workaround:

None

Further Problem Description:

N/A
