Description
Configure bidirectional failure detection timers and authentication.
The remaining statements are explained separately. See CLI Explorer.
Options
authentication algorithm algorithm-name —Configure the algorithm used to authenticate the specified
BFD session: simple-password, keyed-md5, keyed-sha-1, meticulous-keyed-md5, or meticulous-keyed-sha-1.
authentication key-chain key-chain-name—Associate a security key with the specified BFD session
using the name of the security keychain. The name you specify must
match one of the keychains configured in the authentication-key-chains
key-chain statement at the [edit security] hierarchy
level.
authentication loose-check—(Optional) Configure
loose authentication checking on the BFD session. Use only for transitional
periods when authentication is not configured at both ends of the
BFD session.
detection-time threshold milliseconds—Configure a threshold for the adaptation of the BFD
session detection time. When the detection time adapts to a value
equal to or greater than the threshold, a single trap and a single
system log message are sent.
minimum-interval milliseconds—Configure the minimum interval after which the local routing
device transmits a hello packet and then expects to receive a reply
from the neighbor with which it has established a BFD session. Optionally,
instead of using this statement, you can specify the minimum transmit
and receive intervals separately using the transmit-interval
minimum-interval and minimum-receive-interval statements.
Range: 1 through 255,000 milliseconds
minimum-receive-interval milliseconds—Configure the minimum interval after which the local
routing device expects to receive a reply from a neighbor with which
it has established a BFD session. Optionally, instead of using this
statement, you can configure the minimum receive interval using the minimum-interval statement.
Range: 1 through 255,000 milliseconds
multiplier number—Configure
the number of hello packets not received by a neighbor that causes
the originating interface to be declared down.
Range: 1 through 255
Default: 3
no-adaptation—Configure BFD sessions not to
adapt to changing network conditions. We recommend that you not disable
BFD adaptation unless it is preferable not to have BFD adaptation
enabled in your network.
transmit-interval threshold milliseconds—Configure the threshold for the adaptation of the BFD
session transmit interval. When the transmit interval adapts to a
value greater than the threshold, a single trap and a single system
message are sent. The interval threshold must be greater than the
minimum transmit interval.
Range: 0 through 4,294,967,295 (232 – 1)
transmit-interval minimum-interval milliseconds—Configure a minimum interval after which the local routing
device transmits hello packets to a neighbor. Optionally, instead
of using this statement, you can configure the minimum transmit interval
using the minimum-interval statement.
Range: 1 through 255,000
version—Configure the BFD version to detect: 1 (BFD version 1) or automatic (autodetect
the BFD version).
Default:
automatic
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
