Configuring Bfd Support For Ospf - Cisco Catalyst 4500 Series Configuration Manual

How to Configure Bidirectional Forwarding Detection
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 37-8
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
gigabitethernet 6/1
Step 5
end
Switch(config-router) end
Step 6
show bfd neighbors [details]
Switch# show bfd neighbors details
Step 7
show ip eigrp interfaces [type number]
[as-number] [detail]
Switch# show ip eigrp interfaces detail

protocol, see the following sections:

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:

"Configuring BFD Session Parameters on the Interface"
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.
(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.
