Enabling Ospfv3 Ip Frr - Huawei Quidway NetEngine80E Configuration Manual

HUAWEI NetEngine80E/40E Router
Configuration Guide - IP Routing
Applicable Environment
With the development of networks, Voice over IP (VoIP) and on-line video services require
high-quality real-time transmission. Nevertheless, if an OSPFv3 fault occurs, traffic can be
switched to a new link only after the following processes: fault detection at the millisecond level,
notifying the fault to the routing control plane at the millisecond level, generating and flooding
new topology information at the tens of milliseconds level, triggering SPF calculation at the tens
of milliseconds level, and notifying and installing a new route at the hundreds-of-milliseconds
level. As a result, it takes much more than 50 ms to recovery the link from the fault, which cannot
meet the requirement for real-time services on the network.
With OSPFv3 IP FRR that calculates a backup link in advance, devices can fast switch traffic
to the backup link without interrupting traffic when the primary link becomes faulty. This
protects traffic and therefore greatly improves the reliability of OSPFv3 networks.
OSPFv3 IP FRR is applicable to the services that are sensitive to packet delay and packet loss.

6.11.2 Enabling OSPFv3 IP FRR

This section describes how to enable OSPFv3 IP FRR to generate a loop-free backup link. When
this route becomes faulty, OSPFv3 can fast switch the traffic to a backup link.
