Configuring BFD
To remove the BFD parameter configuration, enter the no bfd interval interface configuration
command.
Enabling BFD Routing Protocol Clients
After you configure BFD parameters on an interface, you can start a BFD session for one or more routing
protocols. You must first enable routing by entering the ip routing global configuration command on the
switch. Note that there can be more than one way to start a BFD session on an interface, depending on
the routing protocol.
• Configuring BFD for OSPF, page 29-74
• Configuring BFD for IS-IS, page 29-76
• Configuring BFD for BGP, page 29-77
• Configuring BFD for EIGRP, page 29-78
• Configuring BFD for HSRP, page 29-78
Configuring BFD for OSPF
When you start BFD sessions for OSPF, OSPF must be running on all participating devices.You can
enable BFD support for OSPF by enabling it globally on all OSPF interfaces or by enabling it on one or
more interfaces.
Step 5
bfd interval milliseconds min_rx
milliseconds multiplier value
Set BFD parameters for echo packets on the interface.
• interval—Specify the rate at which BFD echo packets are sent to BFD
peers. The range is from 50 to 999 milliseconds (ms).
• min_rx—Specify the rate at which BFD echo packets are expected to
be received from BFD peers. The range is from 50 to 999 ms.
• multiplier—Specify the number of consecutive BFD echo packets that
must be missed from a BFD peer before BFD declares that it is
unavailable and informs the other BFD peer of the failure. The range is
from 3 to 50.
Note There are no baseline BFD parameter defaults.
Step 6
end Return to privileged EXEC mode.
Step 7
show running-config Verify your entries.
Step 8
show bfd neighbor detail (Optional) Display the final configured or negotiated values when the
session is created with a neighbor.
Step 9
copy running-config startup-config (Optional) Save your entries in the configuration file.
