Configuring BFD Support for Layer 3 Protocols

After a BFD session 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, IS-IS, OSPF, PIM,
VRRP Tracking, Static Routes). BFD interoperability with Layer 3 protocols is configurable at the router
level to enable BFD session globally, or at the interface level for specific interfaces only.
The following sections provide information about how to configure BFD support for BGP, IS-IS, OSPF,
PIM, VRRP Tracking, and Static Routes:
"Configuring BFD Support for BGP" on page 20-18.
"Configuring BFD Support for IS-IS" on page 20-21
"Configuring BFD Support for OSPF" on page 20-23.
"Configuring BFD Support for PIM" on page 20-26
"Configuring BFD Support for VRRP Address Tracking" on page 20-30.
"Configuring BFD Support for Static Routes" on page 20-31.
Configuring BFD Support for BGP
The steps below show how to configure and verify BFD support for the BGP protocol, so that BGP is a
registered protocol with BFD and receives forwarding path detection failure messages from BFD.
Note. BFD must be configured and enabled on the participating BGP interfaces. See
Session Parameters" on page 20-14

To associate BGP protocol with BFD liveliness detection, register BGP with BFD at the protocol level
using the ip bgp bfd-state
-> ip bgp bfd-state enable
The BFD status for the BGP protocol is now enabled, which means that communication between BGP and
BFD is enabled. To de-register BGP with BFD, enter the following command:
-> ip bgp bfd-state disable
To verify the BFD status for BGP protocol, you can use the show ip bgp command as shown below:
