Configuring BFD

Configuring BFD Support for Layer 3 Protocols

After BFD is configured on all interfaces or on a specific set of individual interfaces, the next step is to
configure BFD interoperability with the supported Layer 3 protocols (BGP, OSPF, VRRP Tracking, Static
Routes). BFD interoperability with Layer 3 protocols is configurable at the router level to enable BFD
globally for all interfaces or sessions, or at the interface level for specific interfaces or sessions only.
The following sections provide information about how to configure BFD support for BGP, OSPF, VRRP
Tracking, and Static Routes:
"Configuring BFD Support for OSPF" on page 30-18.
"Configuring BFD Support for BGP" on page 30-21.
"Configuring BFD Support for VRRP Tracking" on page 30-22.
"Configuring BFD Support for Static Routes" on page 30-24.

Configuring BFD Support for OSPF

The steps below show how to configure and verify BFD support for OSPF, so that OSPF is a registered
protocol with BFD and will receive forwarding path detection failure messages from BFD.
Note. OSPF must be running on all participating routers, and BFD must be configured and enabled on the
participating OSPF interfaces. See
mation.
1
To encapsulate BFD within the OSPF protocol, register OSPF with BFD at the protocol level using the
ip ospf bfd-std status
-> ip ospf bfd-std status enable
The BFD status for the OSPF protocol is now enabled, which means that communication between OSPF
and BFD is enabled. To de-register OSPF with BFD, enter the following command:
-> ip ospf bfd-std status disable
Note. The BFD status for OSPF protocol is disabled by default.

To verify the BFD status for OSPF protocol, use the
