For additional Arista BFD configuration settings and examples, seeSection 37.2: BFD Configurationin the Arista documentation.
Cisco ASA
For Cisco ASA configuration examples, seeBidirectional Forwarding Detection Routingin the Cisco documentation. The BGP configuration is identical to the
IOS/IOS-XE configuration later in this document.
Cisco ASR
To see BFD status, use the following command at the top level of the Cisco AS
configuration:
show bfd neighbors 169.254.44.6 details
To configure BFD on a Cisco ASR, use the following command (the values shown
are examples):
