Configuring BFD Support for EIGRP

This section describes the procedure for configuring BFD support for EIGRP so that EIGRP is a
registered protocol with BFD and will receive forwarding path detection failure messages from BFD.
There are two methods for enabling BFD support for EIGRP:
•
•
Prerequisites
EIGRP 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
To configure BFD support for EIGRP, perform this task:
Command or Action
Step 1
enable
Switch> enable
Step 2
configure terminal
Switch# configure terminal
Step 3
Switch eigrp as-number
Switch(config)# router eigrp 123
Step 4
bfd all-interfaces
or
bfd interface type number
Switch(config-router)# bfd all-interfaces
or
Switch(config-router)# bfd interface

Step 5
end
Switch(config-router) end

You can enable BFD for all of the interfaces for which EIGRP is routing by using the bfd
all-interfaces command in router configuration mode.
You can enable BFD for a subset of the interfaces for which EIGRP is routing by using the bfd
interface type number command in router configuration mode.

Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Configures the EIGRP routing process and enters router
configuration mode.
Enables BFD globally on all interfaces associated with the
EIGRP routing process.
or
Enables BFD on a per-interface basis for one or more
interfaces associated with the EIGRP routing process.
Exits router configuration mode and returns the switch to
privileged EXEC mode.
