Configuring BFD Support for Dynamic Routing Protocols

You can enable BFD support for dynamic routing protocols at the router level to enable BFD support
globally for all interfaces or you can configure BFD on a per-interface basis at the interface level.
This section describes the following procedures:

Configuring BFD Support for BGP
This section describes the procedure for configuring BFD support for BGP so that BGP is a registered
protocol with BFD and will receive forwarding path detection failure messages from BFD.
Prerequisites
BGP must be running on all participating switches.
The baseline parameters for BFD sessions on the interfaces over which you want to run BFD sessions to
BFD neighbors must be configured. See the
section on page 40-8
To configure BFD support for BGP, perform this task:
Command or Action
Step 1
enable
Switch> enable
Step 2
configure terminal
Switch# configure terminal
Step 3
router bgp as-tag
Switch(config)# router bgp tag1
Step 4
neighbor ip-address fall-over bfd
Switch(config-router)# neighbor 172.16.10.2
fall-over bfd
