Configuring Bfd For Eigrp; Configuring Bfd For Hsrp - Cisco 3845 - Security Bundle Router Software Manual

Configuring BFD
Command
Step 3
neighbor ip-address fall-over bfd
Step 4
end
Step 5
show bfd neighbors [detail]
>
show ip bgp neighbor
Step 6 copy running-config startup-config
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:
Command
Step 1
configure terminal
Step 2
router eigrp as-number
Step 3 log-adjacency changes [detail]
Step 4
bfd {all-interfaces | interface
interface-id}
Step 5 end
Step 6 show bfd neighbors [detail]
Step 7 copy running-config startup-config
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).

Purpose
Enable BFD support for fallover on the BFD neighbor.
Return to privileged EXEC mode.
Verify the configuration.
Display information about BGP connections to neighbors.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify an EIGRP autonomous system number, and enter router
configuration mode.
Configure the switch to send a system logging message when an EIGRP
neighbor goes up or down.
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
