BFD neighbors must be configured. See the
section on page 37-8
To configure BFD support for BGP, perform this task:
Command or Action
Step 1
enable
Switch> enable
Step 2
configure terminal
Switch# configure terminal

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:
•

"Monitoring and Troubleshooting BFD" section on page 37-16
Configuring BFD Support for EIGRP, page 37-9
Configuring BFD Support for OSPF, page 37-10
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.
