Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 19: Introduction

    The MTBF indicates the probability of faults. It is an index of reliability. The MTBF is the predicted elapsed time between inherent failures of a system during operation, usually in hours. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 20: Levels Of Reliability Requirements

    The active and standby nodes connect to convergence nodes. Devices of convergence layer are dual-homed to single node multi-device of the upper layer or to multi-node device of Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

    End-to-end protection: 1:1, 1+1, 1:N, and M:N Local protection: BFD trigger, FRR technology, and OAM technology The trigger mode includes BFD trigger mode and Fast Reroute (FRR) trigger mode. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 22: Reliability Technologies Supported By The Ne80E/40E

    Compared with fast convergence in IGP, the LDP FRR calculates a secondary interface in advance. Route calculation and re-establishment of an LSP after a failure take less time. As a result, the switchover speeds up. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
  • Page 23 LSP tunnel status corresponding to this forwarding entry. If the LSP tunnel is unavailable, the engine uses the route of a inferior priority carried in this forwarding entry to forward packets. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 24: Oam (Operation Administration & Maintenance)

    Router Redundancy Protocol (VRRP) is a fault-tolerant protocol defined in RFC 3768. VRRP solves the problem of route selection among egress gateways by separating the physical devices from logical devices. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 25: Bfd (Bidirectional Forwarding Detection)

    1-2, LDP LSP serves as a public network tunnel and TE is enabled with QoS between P devices. This network deployment enhances the QoS across the entire network Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 26: Link Failure During Transmission

    With fast detection performed by the OAM, the protection group is listed in the forwarding table with its primary tunnel entry and bypass tunnel entry. This enables fast switchover after a failure is detected, providing high reliability for network connectivity. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.
  • Page 27 If one end does not receive the detection packets within a specified period, the end assumes that the link is interrupted and reports to related modules to perform switchover. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 28: Failure On The Remote Pe - Vpn Frr

    Similar to other FRR technologies, in the VPN FRR, an available bypass path is reserved for fast switchover before the primary path fails. For VPN FRR, two next hops (PEs) are reserved Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 29: Failure Of Downlink Interface On The Pe - Ip Frr

    Then, the private network neighbor relationship between PE1 and PE2 needs to be created, and the primary and bypass paths are created for PE1 accessing CE. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 30: Interface Backup Configuration

    Interface backup is performed in active/standby mode or load balancing mode. Familiarize yourself with the configuration procedures against the networking diagram. Each configuration example consists of the networking requirements, configuration roadmap, configuration procedures, and configuration files. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 31: Introduction Of Interface Backup

    Any physical interface or sub-interface like POS ,Ethernet or ATM interface serves as an active interface on a router. An active interface with larger bandwidth provides a higher transmission rate. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 32: Characteristics Of The Interface Backup Supported By The Ne80E/40E

    When the data flow of the active interface reaches the specified upper limit, the router automatically enables an available standby interface with the highest priority. Both interfaces undertake the transmission together and share the load. Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 33: Configuring The Active/Standby Interface Backup

    Pre-configuration Tasks Before configuring the active/standby interface backup, complete the following tasks: Configuring physical parameters for interfaces Configuring link layer attributes for interfaces Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

  • Page 34: Configuring A Standby Interface

    A main interface can be configured with a maximum of three standby interfaces. In addition, a standby interface can be configured only for one main interface. l A maximum of 10 main interfaces can exist at the same time. ----End Issue 02 (2011-09-10) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

BFD for LSP BFD detects failures in an MPLS LSP forwarding path on the data plane. As the format of BFD packets is unchanged, the BFD packets are easily transmitted through hardware and traverse through firewalls.

NOTE For the configuration of BFD for PW, refer to the chapter "PWE3 Configuration" in the HUAWEI NetEngine80E/40E Router Configuration Guide - VPN. BFD for PIM The NE80E/40E supports the dynamic creation of a BFD session between PIM neighbors, which is used to detect faults in links between the PIM neighbors.
