Bidirectional Forwarding Detection (BFD)
Overview
Bidirectional Forwarding Detection (BFD) is a detection protocol that provides fast forwarding path
failure detection. The FTOS implementation is based on the standards specified in the IETF Draft
draft-ietf-bfd-base-03 and supports BFD on all Layer 3 physical interfaces including VLAN interfaces
and port-channels.
BFD is supported on the C-Series and E-Series, where indicated by the
c and e characters under
command headings.
BFD is supported on E-Series ExaScale e
x
with FTOS 8.2.1.0 and later.
