Command Function
DES-7200(config-router)# exit
(Optional) Exit the Router configuration mode
and return to the global configuration mode.
DES-7200(config)# interface type
number
(Optional) Enter the interface configuration
mode.
DES-7200(config-if)# ip rip bfd
[disable]
(Optional) Enable or disable the BFD for
OSPF on a specified interface.
DES-7200(config-if)# end
(Optional) Exit to the privileged mode.
DES-7200# show bfd neighbor
[details]
(Optional) Show the information of the BFD
session establishment and whether OSPF is
associated to the specified session.
DES-7200# show ip ospf
(Optional) Verify whether OSPF is associated
to the specified session.
Use the no bfd all-interfaces command in the Router configuration mode to
disable the BFD for OSPF on all interfaces.
The following example shows how to enable the BFD for OSPF on all interfaces
excluding the FastEthernet 0/2:
DES-7200# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
DES-7200(config)# router ospf 123
DES-7200(config-router)# bfd all-interfaces
DES-7200(config-router)# exit
DES-7200(config)# interface FastEthernet 0/2
DES-7200(config-if)# ip rip bfd disable
DES-7200(config-if)#end
Caution
The BFD for OSPFv3 is not supported in firmware v10.4(1) and
v10.3(4b3).
Before enabling BFD for OSPF, the BFD session parameter
must be configured, or it is ineffective.
The BFD session cannot be established if the specified interface
and the actual outbound interface for the BFD packets are
inconsistent because of the IP routing.
The BFD session cannot be established if the specified interface
and the actual incoming interface for the BFD packets are
inconsistent.
BFD monitoring is not supported in the virtual link of
OSPFv2/OSPFv3.
