Chapter 29 Configuring IP Unicast Routing
Configuring BFD
To disable BGP BFD, enter the no neighbor ip-address fall-over bfd router configuration command.
Configuring BFD for EIGRP
When you start BFD sessions for EIGRP, EIGRP must be running on all participating devices.You can
enable BFD support for EIGRP by globally enabling it on all EIGRP interfaces or by enabling it on one
or more interfaces.
Beginning in privileged EXEC mode, follow these steps follow these to configure EIGRP BFD:
To disable EIGRP BFD on all interfaces, enter the no bfd all-interfaces router configuration command.
To disable it on an interface, enter the no bfd interface interface-id router configuration command.
Configuring BFD for HSRP
HSRP supports BFD by default; it is globally enabled on all interfaces. If HSRP support has been
manually disabled, you can reenable it in interface or global configuration mode. All participating
devices must have HSRP enabled and CEF enabled (the default).
Step 3
neighbor ip-address fall-over bfd Enable BFD support for fallover on the BFD neighbor.
Step 4
end Return to privileged EXEC mode.
Step 5
show bfd neighbors [detail]
>
show ip bgp neighbor
Verify the configuration.
Display information about BGP connections to neighbors.

Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
router eigrp as-number Specify an EIGRP autonomous system number, and enter router
configuration mode.
Step 3
log-adjacency changes [detail] Configure the switch to send a system logging message when an EIGRP
neighbor goes up or down.
Step 4
bfd {all-interfaces | interface
interface-id}
Enable BFD for EIGRP.
• Enter all-interfaces to globally enable BFD on all interfaces
associated with the EIGRP routing process
• Enter interface interface-id to enable BFD on a per-interface basis for
one or more interfaces associated with the EIGRP routing process.
Step 5
end Return to privileged EXEC mode.
Step 6
