IP Routing: BFD Configuration Guide

Cisco IOS XE Everest 16.6

Introduction to Bidirectional Forwarding Detection (BFD)

This document details the configuration of the Bidirectional Forwarding Detection (BFD) protocol within Cisco IOS XE Everest 16.6. BFD is a crucial detection protocol designed to offer rapid forwarding path failure detection across diverse media types, encapsulations, topologies, and routing protocols. It includes guidance on setting up multihop BFD sessions.

BFD offers network administrators a standardized method for failure detection, complementing fast forwarding path failure detection. By enabling consistent detection rates, BFD simplifies network profiling and planning, leading to more predictable reconvergence times.

Key Topics Covered

  • Finding Feature Information
  • Prerequisites and Restrictions for BFD
  • BFD Operation and Neighbor Relationships
  • BFD Support for various routing protocols (EIGRP, IS-IS, OSPF, HSRP, Static Routing)
  • BFD configuration for specific scenarios like DMVPN and IPv6
  • Monitoring and Troubleshooting BFD
  • Configuration Examples for BFD
