7.19 Configuring IPv6 IS-IS Auto FRR
With IPv6 IS-IS Auto FRR, traffic on a faulty link can be quickly switched to the backup link
of the faulty link. This ensures that the traffic interruption time is within 50 ms and improves
the reliability of IS-IS networks.
7.19.1 Before You Start
Before configuring IPv6 IS-IS Auto FRR, familiarize yourself with the usage scenario, complete
the pre-configuration tasks, and obtain the data required for the configuration.
Applicable Environment
As the network keeps developing, services such as Voice over IP (VoIP) and on-line video
services require high-quality real-time transmission. Nevertheless, if an IS-IS fault occurs, traffic
can be switched to a new link only after the following processes: fault detection, LSP update,
LSP flooding, route calculation, and FIB entry delivery. As a result, traffic is interrupted for
much more than 50 ms, which cannot meet the requirement for real-time services on the network.
With IPv6 IS-IS Auto FRR, devices can rapidly switch traffic from faulty links to backup links
without interrupting the traffic. This protects traffic and greatly improves the reliability of IS-
IS networks. The NE80E/40E supports IPv4 IS-IS Auto FRR.
IPv6 IS-IS Auto FRR is applicable to the services that are very sensitive to packet delay and
packet loss.
