5.17.4 Example for Configuring Single-hop BFD for a Layer 3 Eth-
Trunk Member Link

In this example, a single-hop BFD session is configured to rapidly check direct links between
two Eth-Trunk sub-interfaces.

Networking Requirements

On a network shown in

Figure 5-7

, an Eth-Trunk link composed of two GE links exists between

Router A and Router B.

BFD is performed on the member link GE 1/0/0.

Configuration Roadmap

The configuration roadmap is as follows:

Create an Eth-Trunk interface.

Configure single-hop BFD for a specified member link.

Data Preparation

To configure the one-hop BFD for Layer 3 Eth-Trunk member link, you need the following data:

Peer IP address for a BFD session, which is the IP address of an Eth-Trunk member link

Local member link interface sending and receiving BFD control packets

Local and remote discriminators of a BFD session

NOTE

Default values of the minimum sending interval, minimum receiving interval, and local detection multiplier
for BFD control packets are used.

Procedure

Step 1

Configure an Eth-Trunk interface.

# Create an Eth-Trunk interface on Router A.
