Usage Guidelines There are two methods to configure routing protocols to use BFD for failure detection. To enable BFD
for all neighbors of a routing protocol, enter the bfd all-interfaces command in router configuration
mode. If you do not want to enable BFD on all interfaces, enter the bfd interface command in router
configuration mode.
Examples The following example shows BFD enabled for all Intermediate System-to-Intermediate System (IS-IS)
neighbors:
Router> enable
Router# configure terminal
Router(config)# router isis tag1
Router(config-router)# bfd all-interfaces
Router(config-router)# end
The following example shows BFD enabled for all Open Shortest Path First (OSPF) neighbors:
Router> enable
Router# configure terminal
Router(config)# router ospf 123
Router(config-router)# bfd all-interfaces
Router(config-router)# end
