|
:abbr:`BFD (Bidirectional Forwarding Detection)` is described and extended by
|
|
the following RFCs: :rfc:`5880`, :rfc:`5881` and :rfc:`5883`.
|
|
|
|
|
|
Configure BFD
|
|
=============
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address>
|
|
|
|
Set BFD peer IPv4 address or IPv6 address
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> echo-mode
|
|
|
|
Enables the echo transmission mode
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> multihop
|
|
|
|
Allow this BFD peer to not be directly connected
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> source
|
|
[address <address> | interface <interface>]
|
|
|
|
Bind listener to specifid interface/address, mandatory for IPv6
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> interval echo-interval <10-60000>
|
|
|
|
The minimal echo receive transmission interval that this system is
|
|
capable of handling
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> interval multiplier <2-255>
|
|
|
|
Remote transmission interval will be multiplied by this value
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> interval
|
|
[receive | transmit] <10-60000>
|
|
|
|
Interval in milliseconds
|
|
|
|
.. cfgcmd:: set protocols bfd peer <address> shutdown
|
|
|
|
Disable a BFD peer
|
|
|
|
|
|
Enable BFD in BGP
|
|
-----------------
|
|
|
|
.. cfgcmd:: set protocols bgp <asn> neighbor <address> bfd
|
|
|
|
Enable BFD on a single BGP neighbor
|
|
|
|
.. cfgcmd:: set protocols bgp <asn> peer-group <group> bfd
|
|
|
|
Enable BFD on a BGP peer group
|
|
|
|
|
|
|
|
Enable BFD in OSPF
|
|
------------------
|
|
|
|
.. cfgcmd:: set interfaces ethernet <ethN> ip ospf bfd
|
|
|
|
Enable BFD for ospf on a interface
|
|
|
|
.. cfgcmd:: set interfaces ethernet <ethN> ipv6 ospfv3 bfd
|
|
|
|
Enable BFD for ospfv3 on a interface
|
|
|
|
|
|
|
|
Operational Commands
|
|
====================
|
|
|
|
.. opcmd:: show protocols bfd peer
|
|
|
|
Show all BFD peers
|
|
|
|
.. code-block:: none
|
