Router configuration (config-router) and address-family interface configuration (config-router-af) Command History To disable BFD for all neighbors on a single interface, use the no form of this command.īFD is disabled on the interfaces participating in the routing process. This command was integrated into Cisco IOS Release 12.0(31)S. This command was integrated into Cisco IOS Release 12.4(4)T. This command was integrated into Cisco IOS Release 12.2(33)SRA. This command was integrated into Cisco IOS Release 2.1 XE and implemented on the Cisco ASR 1000 Series Aggregation Services Routers. The bfd all-interfaces command in named router configuration mode was replaced by the bfd command in address-family interface mode. Support for the Routing Information Protocol was added. There are two methods to configure routing protocols to use BFD for failure detection. To enable BFD for all interfaces, enter the bfd all-interfaces command in router configuration mode.

In Cisco IOS Release 12.4(24)T, Cisco IOS 12.2(33)SRA and earlier releases, the bfd all-interfaces command works in router configuration mode and address-family interface mode. In Cisco IOS Release 15.0(1)M and later releases, the bfd all-interfaces command in named router configuration mode is replaced by the bfd command in address-family interface configuration mode.

The following example shows how to enable BFD for all EIGRP neighbors, using the bfd command in address-family interface configuration mode: Router> enable The following example shows how to enable BFD for all Open Shortest Path First (OSPF) neighbors: Router> enable The following example shows how to enable BFD for all Intermediate System-to-Intermediate System (IS-IS) neighbors: Router> enable Router(config-router)# bfd all-interfaces The following example shows how to enable BFD for all Enhanced Interior Gateway Routing Protocol (EIGRP) neighbors: Router> enable Use the bfd command in address-family interface configuration mode to achieve the same functionality as that of the bfd all interfaces command in router configuration mode.
