Introduction

This document describes the various Bidirectional Forwarding Detection (BFD) flap-reasons on a Cisco vEdge router.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco SDWAN solution.

Components Used

This document is based on Cisco cloud vEdge router running 19.2.1.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Topology Overview

This document is not restricted to any specific topology.

BFD States

The possible values of 'flap-reason' on a Cisco vEdge router are:

1. bfd-deleted - BFD goes down because the control plane has deleted it.

You raise two notifications when BFD is deleted. One for BFD down and one when BFD gets deleted.

2. timeout - No BFD response from the remote end.

3. remote-down - Remote end sent a BFD packet that indicates that it has gone to down-state.4.

4. na - not applicable. This is set when the BFD session is created for the first time and when the BFD session comes up.

Scenarios

Scenario 1. flap-reason:bfd-deleted

Perform a port-hop on VEDGE-1 router and reproduce this scenario:

You can also clear a control connection on VEDGE-1 in order to test this scenario (which also disables a TLOC):

Scenario 2. flap-reason:timeout

You can reproduce this scenario by disabling a TLOC (biz-internet in this case) on VEDGE-1 by shutting down an interface in the underlay.

BFD state on VEDGE-2 before you disable a TLOC on VEDGE-1 side:
