Configuring BFD Support for OSPF

This section describes the procedures for configuring BFD support for OSPF so that OSPF is a registered
protocol with BFD and will receive forwarding path detection failure messages from BFD. You can
either configure BFD support for OSPF globally on all interfaces or configure it selectively on one or
more interfaces.
There are two methods for enabling BFD support for OSPF:
•
•
See the following sections for tasks for configuring BFD support for OSPF:

•
Configuring BFD Support for OSPF for All Interfaces
To configure BFD for all OSPF interfaces, perform the steps in this section.
If you do not want to configure BFD on all OSPF interfaces and would rather configure BFD support
specifically for one or more interfaces, see the
Interfaces" section on page
Prerequisites
OSPF must be running on all participating switches.
The baseline parameters for BFD sessions on the interfaces over which you want to run BFD sessions to
BFD neighbors must be configured. See the
section on page 39-8

You can enable BFD on all the interfaces for which OSPF is routing by using the bfd all-interfaces
command in router configuration mode. You can disable BFD support on individual interfaces using
the ip ospf bfd [disable] command in interface configuration mode.
You can enable BFD on a subset of the interfaces for which OSPF is routing by using the ip ospf
bfd command in interface configuration mode.

Purpose
(Optional) Verifies that the BFD neighbor is active and
displays the routing protocols that BFD has registered.
(Optional) Displays the interfaces for which BFD support
for EIGRP has been enabled.
