5.16 Configuration Examples

The following sections provide several examples for configuring fast BFD link detection.

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.

5.16.1 Example for Configuring Single-hop BFD for a Layer 3

Physical Link

In this example, a single-hop BFD session to detect faults in a Layer 3 physical link is configured

to rapidly check a direct link on a network.

Networking Requirements

Configuration Roadmap

The configuration roadmap is as follows:

Data Preparation

To complete the configuration, you need the following data:

Issue 02 (2011-09-10)

In this example, interface numbers and link types on the NE40E-X8 are used. On existing networks, the

interface numbers and link types are different from those used in this example.

POS interfaces cannot be configured on the -X1 or -X2 models of NE80E/40Es.

Configure a BFD session on Router A to detect the directly-connected link between Router

A and Router B.

Configure a BFD session on Router B to detect the directly-connected link between Router

B and Router A.
