PurposeCommand or Action
Sets the BFD minimum interval. Range is 15-30000
milliseconds.

Example:
Step 6
RP/0/RP0/CPU0:router(config-bgp-nbr)#bfd
minimum-interval 6500
Sets the BFD multiplier. This is optional, by default the
multiplier will be 3 for all protocols

Configure BFD Under a Dynamic Routing Protocol or Use a Static Route
To establish a BFD neighbor, complete at least one of the following procedures to configure BFD under a
dynamic routing protocol or to use a static route:
Enable BFD for OSPF on an Interface
Perform the following steps to configure BFD for Open Shortest Path First (OSPF) on an interface. The steps
in the procedure are common to the steps for configuring BFD on IS-IS and MPLS-TE; only the command
mode differs.
BFD per interface configuration is supported for OSPF and IS-IS only.
Note
Router# configure
/* Enter OSPF configuration mode to configure the OSPF routing process. */
Router(config)# router ospf 0
/* Set the BFD minimum interval. The range is from 15 to 30000 milliseconds. */
Router(config-ospf)# bfd minimum-interval 6500
/* Set the BFD multiplier. */
Router(config-ospf)# bfd multiplier 7
/* Configure an Open Shortest Path First (OSPF) area. */
Router(config-ospf)# area 0
/* Enter interface configuration mode. */
Router(config-ospf-ar)# interface gigabitEthernet 0/3/0/1
/* Enable BFD to detect failures in the path between adjacent forwarding engines. */
Router(config-ospf-ar-if)# bfd fast-detect
